Select the most appropriate option that can substitute the underlined segment in the given sentence.
During the preparation for competitive exams, Meena avoided going to parties.

The correct answer is "steered clear of".

Let's break down the meaning of the underlined phrase and the given options to find the most appropriate substitution:
The original sentence is: "During the preparation for competitive exams, Meena avoided going to parties."
Here, "avoided going to" means keeping away from or staying away from parties to focus on her studies.

Now, let's analyze the options:
1. "steered clear of": This is an idiomatic expression that means to avoid someone or something that seems unpleasant, dangerous, or undesirable (e.g., avoiding distractions like parties). This fits the context perfectly.
2. "cracked a joke": This means to say something funny, which is irrelevant to avoiding parties.
3. "fired a cracker": This means to burst a firecracker, which makes no sense in this context.
4. "whispered a secret": This means to speak quietly to share private information, which is also irrelevant.

Therefore, the idiom "steered clear of" is the most appropriate substitute for the underlined segment "avoided going to".
