dont know if that makes any sense to you but yeah 'B' is the answer, if it isnt im stoopid but im not
Answer:
1 day.
Explanation:
From the given information:
The rate of mutation induced by RNA polymerase is:

Since the genome comprise of 19000 bp;
To complete a single replication, the viral cycle induce: 

However, in a single day; 10,000,000,000 viruses are reported to be replicated.
Hence, if a virus has 2 mutations; Then 10,000,000,000 virus will have:

SO, to round this up to whole number, it will take 1 day (s) to overcome the therapy.
