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) Carbon nanoflorets made by IIT Bombay researchers can
(B) Aga Khan Foundation has given women in the Bihar district a
(C) The Deep Ocean Mission (DOM) is India’s ambitious quest to explore
Column-II
(D) convert incident sunlight to heat with 87% efficiency.
(E) will require technologies to access the valuable minerals from the ocean-bed
(F) new source of income with state-of-the-art agricultural technology.

The correct answer is A-D & B-F.

To find the correct combination, we must pair the phrases from Column-I with those in Column-II to form grammatically correct and contextually meaningful sentences:

1. Pairing A and D:
Sentence: "Carbon nanoflorets made by IIT Bombay researchers can convert incident sunlight to heat with 87% efficiency."
This combination is grammatically correct. The modal verb "can" in phrase (A) is correctly followed by the base verb "convert" in phrase (D), making logical sense as it describes the capability of the nanoflorets.

2. Pairing B and F:
Sentence: "Aga Khan Foundation has given women in the Bihar district a new source of income with state-of-the-art agricultural technology."
This combination is grammatically and contextually correct. The indefinite article "a" at the end of phrase (B) correctly precedes the noun phrase starting with the consonant sound "new source..." in phrase (F).

3. Pairing C and E:
Sentence: "The Deep Ocean Mission (DOM) is India’s ambitious quest to explore will require technologies to access the valuable minerals from the ocean-bed."
This combination is grammatically incorrect because the verb "explore" in phrase (C) is followed directly by the auxiliary verb "will require" in phrase (E) without a proper subject or relative pronoun (like "which") to connect them.

Therefore, only the pairs A-D and B-F form correct and coherent sentences, making A-D & B-F the correct choice.
