Answer:
The correct answer would be option C.
The frameshift mutation is a type of mutation in which the reading frame of the codons is changed.
Consequently, the sequence of amino acids also gets changed due to which altered or non-functional protein is synthesized.
It is caused by either by addition or deletion of base pair(s) in the DNA sequence of a gene.
For example, reading frame of ABCDEFGHUJKL would be ABC DEF GHI JKL.
Reading frame after addition of Z at fourth position, that is, ABCZDEFGHIJKL, would be ABC ZDE FGH IJK L.
