State entry problem is whether we will ever enter a given state or not.
Now if i say whether we would start from starting state or not then it will not be state entry problem right ?
Similarly...here we need to check whether it would leave the starting state or not.
and since it is the starting state only so we can check using the transitions which are given for the machine whether it would ever leave the starting state or not.
Can u tell me, if reasoning of C) is correct here https://gateoverflow.in/20404/tifr2011-b-25
