In each question two columns are given, each containing three phrases/sentences.
Choose the option that will connect the phrases to form meaningful and correct sentences.

Column-I
(A) Jawaharlal Nehru laid the foundation stone of the National Museum in
(B) The feeling a person develops by practising devotion is unique
(C) Scientists believe that underwater mountains formed
Column-II
(D) through volcanic activity are potentially rich in cobalt.
(E) Sobha Singh who built many of Lutyens’ buildings before independence.
(F) a job we most cherish, and bhakti is an excellent activity.

The correct option is C-D.

To solve this sentence connector question, we need to analyze the phrases given in Column-I and Column-II to find the pair that forms a grammatically correct and meaningful sentence.

Analyzing the pairs:
1. (A) - (E): "Jawaharlal Nehru laid the foundation stone of the National Museum in" + "Sobha Singh who built many of Lutyens’ buildings before independence."
This combination is grammatically incorrect and incomplete as the phrase ending with "in" requires a location or a year, not a name.

2. (B) - (F): "The feeling a person develops by practising devotion is unique" + "a job we most cherish, and bhakti is an excellent activity."
This does not create a cohesive or syntactically correct sentence.

3. (C) - (D): "Scientists believe that underwater mountains formed" + "through volcanic activity are potentially rich in cobalt."
This combination is logically coherent and grammatically complete. "Underwater mountains formed through volcanic activity are potentially rich in cobalt" properly completes the clause introduced by "Scientists believe that...".

Therefore, the only correct combination that forms a meaningful sentence is C-D.
