Is my reasoning correct?

#1

the h11 function is shifted to the right because of +24 bias and h12 graph is shifted right because of -24 bias …when we subtract h11 plot with h12 it yields some a graph similar to third option

#2

Hey @Lakshita, yes its apt enough for the question. I will also do something like this.

Hope this resolved your doubt.
Plz mark it as resolved in my doubts section.
