Solution
The correct option is
B
(
∼
p
)
∧
(
∼
q
)
Given
p
:
"She is beautiful"
and
q
:
"She is intelligent"
Given conjugation is "She is neither beautiful nor intelligent"
This is just another way of saying "She is not beautiful and she is not intelligent"
∼
p
:
"She is not beautiful"
and
∼
q
:
"She is not intelligent"
Thus
(
∼
p
)
∧
(
∼
q
)
means "
She is not beautiful and she is not intelligent" or "
She is neither beautiful nor intelligent"
