All A's, B's, C's, D's, E's and F's are Q's.
All A's are B's.
No B that is not A is an F.
Some C's are A's
All D's are C's.
Some C's are not B
No D is an A.
All Q's and only Q's that are neither B's nor C's are E's.

If P is not a B, which of the following must be true?

The question is based on the following:
$\left(1\right)$ Each word in a horizontal row must begin with a successive letter.
$\left(2\right)$ Each word in a vertical column must begin with a different letter.
$\left(3\right)$ Each word in a horizontal row must have the same number of letters.
$\left(4\right)$ Each word in a vertical column must have a different number of letters.
$\left(5\right)$ Each word in a vertical column must be the same part of speech.
