Question

Answer 1

Question Number 10

From graph we can infer the fact

T1 should be executed first

T3 should be executed before T4

there is no relation with respect to ordering for T3 and T2 , also T4 and T2, so T2 can be anywhere after T1

Option D is wrong since T4 is coming before T 3

Comments

Answer 2

Make the dependency graph..in that T3 is required for the execution of T4..hence Option D
