The correct answer is E-processing of exons in mRNA that results in a single gene coding for multiple proteins.
Explanation
Splicing is the process where introns are cut out of the mRNA so only the coding parts for proteins. In this way, genes can code for many proteins, depending on how the amino-acids are arranged.
I am not entirely sure what you mean by "responding variable" but I'm going to guess it was the vinegar since it has been used as a perservative for years.
