I am not able to get any of the options. What i have read id that we exacute an instruction that would be anyways executed, independent of the branch condition .For eg in quest no. 77) , I4 would be anyways expected , so this is the instruction we execute after branch (not in order) to avoid branch penalty.
as for this question,
a) if we execute instruction following conditional branch, it would be same a snormal flow of thw program and may case branch penalty if branch condition evaluates to false
b) as per the suggested article, i ma not able to understand the concept of fall through path. in first case it says condition on evaluation of if as true as fall through and its different for the other one.
c) first instruction in taken path is same as option a)
d) its wrong because branching will take same time to execute
please help me clear the concept.
