Question

The following figure represents a logic symbol, this is equivalent to : (A) NAND gate (B) NOT gate (C) OR gate (D) AND gate

Tardigrade Admin · Accepted Answer

This is a combination of logic gates, the first one represents NAND gate,
it will make

C = A B

,
the spend circuit represents a NOT gate
Hence, it makes

Y = \overline{A B} = A B

So, equivalent circuit represents AND gate
