The correct answer to the question is option A.
NEBULA
The object shown in the image is known as a nebula.
Explanation: A nebula is found in interstellar space,it has a form of a giant cloud of dust. When some stars goes into dying process,they explode throwing out gas and dust which forms a nebula.(a supernova remnants nebulae).
Some nebulae(singular form of nebula) are also found where new stars are being formed.
Nebula are the basic building blocks of the universe,they are made up 90% hydrogen,10% helium and other heavier elements in trace amounts from which stars and other solar systems are made.
Nebula exist in 5 distinct types namely;
Emission nebulae, Reflection nebulae,Dark nebulae, Planetary Nebulae and supernova remnants Nebulae.
The given question says that b species diverged around 60,000 year ago from species a. Since the divergence, they have a nucleotide difference of 15 nucleotide.
We need to find out the nucleotide difference in another 240,000 year, which means a total of 300,000 year since divergence.
The nucleotide difference in 60,000 years = 15 nucleotide.
The nucleotide difference in 1 year = nucleotide.
The nucleotide difference in 300,000 years = nucleotide.
The nucleotide difference in 300,000 years = 75 nucleotide.
Hence, after another 240,000 years or 300,000 years since divergence, the species and species b would show a difference of 75 nucleotide.
In another 240,000 years, there would be 60 nucleotide difference, as 15 of the nucleotide are already different in initial 60,000 years from the total of 75 nucleotide difference in 300,000 years. So, 60 (75-15) nucleotide difference would be observed in next 240,000 years.
