Detailed Solution

Concept: One billion stars, on average, are thought to be present in our Milky Way. Helium and hydrogen are the two elements that give stars their sparkling appearance in the night sky.
The Proxima Centauri star system is home to it. The triple-star system, which is 4.37 light-years distant, is the location. It is 4.24 light years distant from Proxima Centauri.
Only two stars, Alpha Centauri A and Tau Ceti, have spectral types G, which are similar to our sun, out of all the stars that are closer to us than 15 light-years. The bulk of red dwarf stars are M-type.
Only nine of the stars in this whole system are bright enough to be seen from Earth with the unaided eye.
The answer is  MACS J1149+2223 Lensed Star 1.
Hence, option 1 is correct.
