In TTL an open terminal is always "high" 1. So B will be at the output. B= pulses.

Doesn't 'open' mean no current in that wire i.e. HighZ, makes first input undriven.
Answer should be "an Undefined level".
Answer should be "an Undefined level".

How to get pulses because one of the input is open it means "0" so output should be 0?

If the o/p of inverter is open that means 0 and for B I/p is pulse means 1 so the o/p become 0.
