Answer : 2. "Pessimistic"
Explanation :

To find the antonym of "optimistic," we first need to understand its meaning. "Optimistic" refers to having a positive and hopeful outlook on life, expecting good things to happen.

Now, let's evaluate the options:

• a) Hopeful: This is a synonym of "optimistic," as it also means having hope and expecting positive outcomes.
• b) Pessimistic: This is the opposite of "optimistic." A pessimistic person expects negative outcomes and tends to focus on the downside of situations.
• c) Positive: This is another synonym of "optimistic," meaning having a positive outlook.
• d) Cheerful: This means being happy and in good spirits, which aligns with being optimistic but is not its direct antonym.

Therefore, the antonym of "optimistic" is b) Pessimistic.
