Complete the sentence meaningfully using the best possible starter. Choose the option that most effectively conveys the sequence and impact described in the original sentences.

(I) The RBI has tightened norms for unsecured personal loans citing rising household debt levels.

(II) Several non-banking financial companies have reported a sharp drop in loan disbursals this quarter.

(A) Although borrowers welcomed the move as it reduces their repayment burden...

(B) Since stricter regulations have directly impacted lending activity...

(C) While critics say the norms were long overdue given the debt concerns...

To determine the most effective starter that connects the two sentences meaningfully, let us analyze the relationship between them:

Sentence (I): The RBI has tightened norms for unsecured personal loans citing rising household debt levels. (This describes a cause: regulatory tightening due to debt concerns.)
Sentence (II): Several non-banking financial companies (NBFCs) have reported a sharp drop in loan disbursals this quarter. (This describes the effect: a decrease in lending activity.)

Thus, we are looking for a starter that establishes a cause-and-effect relationship, where the tighter regulations (cause) lead to the drop in loan disbursals (effect).

Let us evaluate each of the given starters:

Starter (A): "Although borrowers welcomed the move as it reduces their repayment burden..."
This starter introduces a contrast ("Although"). However, the relationship between tighter loan norms and decreased disbursals is direct cause-and-effect, not a contrast. Moreover, tighter norms generally make borrowing harder, which is not typically described as "welcomed" by borrowers for reducing "repayment burden" in this context. Therefore, (A) is incorrect.

Starter (B): "Since stricter regulations have directly impacted lending activity..."
This starter uses "Since" to establish a cause-and-effect relationship. It accurately connects the cause (stricter regulations / tightening of norms by the RBI) directly to the consequence (impacted lending activity / drop in loan disbursals by NBFCs). This yields a coherent and grammatically correct combined sentence. Therefore, (B) is a valid starter.

Starter (C): "While critics say the norms were long overdue given the debt concerns..."
This starter introduces a concession or contrast ("While") and focuses on the opinions of critics regarding whether the norms were overdue. It fails to directly and logically connect the action of tightening norms to the consequence of dropped loan disbursals in a cohesive manner. Therefore, (C) is incorrect.

Comparing the options, only starter (B) effectively conveys the sequence and impact described in the original sentences. Hence, the correct option is "Only B".
