|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.|

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

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

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