Select the appropriate option to fill in the blank in the following sentence:

Everything is going well. We ______ any problems so far.

haven't had

The correct answer is Option (3) → haven't had

The sentence requires the Present Perfect Tense because:

1. The introductory statement, "Everything is going well," indicates a current situation.

2. The phrase "so far" indicates an action or state that started in the past and continues up to the present moment.

• Haven't had (short for have not had) is the correct negative form of the Present Perfect Tense, meaning "We have not experienced problems up to this point in time."
