Answer:

The answer is F.

Step-by-step explanation:

Let $P$ and $Q$ be the propositions "I exercise" and " I feel tired", respectively. Then we want to know what is the negation of $P \land Q$ . Remember that, due to De Morgan's laws, the negation of $P \land Q$ is $\neg P \lor \neg Q$ , that is "I don't exercise or I feel envigorated".

Answer:

G. I don't exercise and I feel envigorated.

Step-by-step explanation:

In this sentence the I exercise and I feel tired you need to say in order tos ay the negation of this sentence would be:

I do not exercise nor feel tired, since there´s no option that says this, we can choose the one that says I don´t exercise, and envigorated is the opposite than tired, so the correct option would be I don´t exercise and I feel envigorated.
