- B$NOR$
- ✓$OR$
- D$AND$
✓
Answer
Correct option: C.
$OR$
c
$\mathrm{Y}=\overline{\overline{\mathrm{A}} \cdot \overline{\mathrm{B}}}=\overline{\overline{\mathrm{A}}}+\overline{\overline{\mathrm{B}}}=\mathrm{A}+\mathrm{B}$
$\mathrm{Y}=\overline{\overline{\mathrm{A}} \cdot \overline{\mathrm{B}}}=\overline{\overline{\mathrm{A}}}+\overline{\overline{\mathrm{B}}}=\mathrm{A}+\mathrm{B}$
