a.

Using a hardcoded offset from the EBP register.

b.

Using a hardcoded offset from the ESP register.

c.

Using a hardcoded offset from the EAX register.

d.

Posted under Reverse Engineering

Answer: (a).Using a hardcoded offset from the EBP register. Explanation:In most stack frames, EBP points to the end of the local variable region, so any code requiring access to a local variable must use EBP and subtract a certain offset from it.
