I think Option D is correct.
As (A.B whole bar = Abar + Bbar) is the result of only NAND gate and (Abar + Bbar=bubbled OR).
As (A.B whole bar = Abar + Bbar) is the result of only NAND gate and (Abar + Bbar=bubbled OR).

Option A is correct.
As ( A.B whole bar = Abar + Bbar) is the result of only NAND gate.
Therefore option A as both gates are NAND in this option only.
As ( A.B whole bar = Abar + Bbar) is the result of only NAND gate.
Therefore option A as both gates are NAND in this option only.

I think option A is correct.
Because, NAND gate output=A.B whole bar=A bar+B bar.
The Output of AND gate is A.B = bubbled output=A.B whole bar.
Because, NAND gate output=A.B whole bar=A bar+B bar.
The Output of AND gate is A.B = bubbled output=A.B whole bar.

Option B is Correct.
A NOR gate and a bubbled input of AND gate.
A NOR gate and a bubbled input of AND gate.

I think it should be: OR gate with bubble on each input is equivalent to a NAND gate.

I think that, the correct answer is D.
Because a NAND is equivalent to after equal term and OR with bubbled output is equivalent for the before equal term.
Because a NAND is equivalent to after equal term and OR with bubbled output is equivalent for the before equal term.
