The correct answer is option a. 1 and 2.
Point d. is incorrect because supernova explosions help to determine distance of the galaxy. This distance is used to compare expansion distance and hence bring to light the history of expansion in the universe. This showed that the universe expansion is increasing and hence get us to know that the expansion of the universe is increasing or accelerating.
