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 option is A-D & B-F.

To form meaningful and grammatically correct sentences, let us connect the phrases from Column-I with those in Column-II based on context and grammar:

1. Phrase (A) + Phrase (D):
(A) "Carbon nanoflorets made by IIT Bombay researchers can"
(D) "convert incident sunlight to heat with 87% efficiency."
Combining these yields: "Carbon nanoflorets made by IIT Bombay researchers can convert incident sunlight to heat with 87% efficiency." This forms a complete, grammatically correct, and factual scientific statement.

2. Phrase (B) + Phrase (F):
(B) "Aga Khan Foundation has given women in the Bihar district a"
(F) "new source of income with state-of-the-art agricultural technology."
Combining these yields: "Aga Khan Foundation has given women in the Bihar district a new source of income with state-of-the-art agricultural technology." This forms a complete, coherent statement regarding socio-economic empowerment.

3. Phrase (C) + Phrase (E):
(C) "The Deep Ocean Mission (DOM) is India’s ambitious quest to explore"
(E) "will require technologies to access the valuable minerals from the ocean-bed"
Combining these does not form a syntactically correct sentence because phrase (C) ends with the transitive verb "explore" which requires a direct object, whereas (E) begins with the auxiliary verb "will require".

Therefore, the valid combinations that yield grammatically correct and meaningful sentences are A-D and B-F.
