The truth table that is visible for the first 16 seconds is *NOT* correct for a NAND gate. It is correct for an AND gate. More correctly for this application, it is an inverted-input NOR gate.
@@ritik4864 The input side of the table uses positive logic: 0 indicates a logical 0 and a low physical voltage. BUT the output side uses negative logic: for the LED to be ON, the physical voltage must be low, but he calls this a (1). The output side On's and Off's are correct, but the indicated logic values (1's and 0's) are incorrect. Truth tables have rules, and shifting between positive and negative logic (also called active-high and active-low), with no notation or explanation, is not allowed.
Sir diode number 1N4007 h kya

It's correct , please check again

You better lay off the voltage my friend.
