C. It is estimated to be stretched over 650 million light years in distance.
Choose the correct answer from the options given below :
Answer: D
All three statements are correct, so the answer is A, B and C.
In July 2017 a team of Indian astronomers announced a previously unknown supercluster of galaxies in the direction of the constellation Pisces, about 4 billion light-years away, and named it Saraswati (A). The team was led by astronomers from the Inter-University Centre for Astronomy and Astrophysics (IUCAA) and the Indian Institute of Science Education and Research (IISER), both in Pune (B).
Saraswati is one of the largest known structures in the nearby universe, estimated to stretch over about 650 million light-years (C). Since all three statements hold, every option that leaves one out is incomplete.
