Answer 1

Answer:

(b) is answer.

Explanation:

Integer overflow attack is not a type of controlhijacking as control-hijacking attack overwrites some data structures in a victim program that affect its control flow, and eventually hijacks the control of the program and possibly the underlying system. ... It causes some of that data to leak out into other buffers, which can corrupt or overwrite whatever data they were holding.
