Correct Option: A
Count is static variable in incr(). Statement static int count = 0 will assign count to 0 only in first call. Other calls to this function will take the old values of count. Count will become 0 after the call incr(0). Count will become 1 after the call incr(1) Count will become 3 after the call incr(2) Count will become 6 after the call incr(3) Count will become 10 after the call incr(4)
