I think option B is also right because if u give two high inputs
the output of the nand gate is low.

Here if any one of the input is low then the output is low for AND gate.

So NAND gate output is high.

So optionC is correct. A B O/P 0 0 1 0 1 1 1 0 1 1 1 0

Yes, the ouput of the nand gate is high if any one of the input is low.

A B T
0 0 1
0 1 1
1 0 1
1 1 0

From truthtable we can easily understand the concept.
