• B. The earth is round and 3+4 =7
• C. It is not that the earth is round or it is not that 3+4 =7
• D. The earth is round or it is not that 3+4 =7

Answer 1

The correct option is C

It is not that the earth is round or it is not that 3+4 =7

p: the earth is round
q: 3+4 =7
~p: It is not that the earth is round
~q: It is not that 3+4 =7
$\sim p\vee \sim q:$ It is not that the earth is round or it is not that 3+4 =7
