Answer 1

The Correct Option is C

To solve the problem, we need to rearrange the given parts to form a coherent sentence.

Given parts: 
(A) Despite the challenges faced by scientists,
(B) they continue to make remarkable progress in understanding the universe,
(C) new discoveries in astrophysics and quantum mechanics,
(D) with many groundbreaking theories being developed every year.

Step-by-step reasoning:
- Part (A) is the introductory clause setting the context.
- Part (B) continues the main idea about what scientists are doing.
- Parts (C) and (D) further explain the type of progress and the nature of developments.
- Part (C) "new discoveries in astrophysics and quantum mechanics," acts as an appositive phrase elaborating on the progress.
- Part (D) "with many groundbreaking theories being developed every year." complements part (C).

Coherent sentence formed:
"Despite the challenges faced by scientists, they continue to make remarkable progress in understanding the universe, new discoveries in astrophysics and quantum mechanics, with many groundbreaking theories being developed every year."

Sequence: A – B – C – D

Final Answer:
The correct sequence is $ {\text{A – B – C – D}} $.
