Answer 2

Answer:

He didn’t try his best

Explanation:

According to the given question. We have to change the sentence in its negative form. Here, the sentence He tried his best is in the present tense and with taking care of meaning we just convert it in negative form. So, we use didn’t make it negative. After adding didn’t we can make the whole sentence in negative form. Did is the present tense marker.
