Select the most appropriate synonym of the underlined word.
Ramya is an ardent follower of secularism.

The correct answer is committed.

Explanation:

The word ardent means very enthusiastic, passionate, or deeply devoted to a cause, belief, or activity.

Let's analyze the given options in the context of the sentence:

1. committed: Displaying dedication and loyalty to a cause or activity. This is the exact synonym for "ardent".

2. forced: Done against one's will or compulsory; unspontaneous.

3. temporary: Lasting for only a limited period of time; not permanent.

4. unhappy: Feeling or showing distress, sadness, or dissatisfaction.

Therefore, replacing "ardent" with "committed" preserves the meaning of the sentence: "Ramya is a committed follower of secularism."
