Correct Answer: ADVANCE

Solution : The correct choice is the second option.

The most appropriate antonym of the given word "INTERFERE" is "ADVANCE".

Interfere : The word interfere means to get involved in or meddle in the affairs or activities of others in a way that disrupts or hinders.

Advance: The word advance is the antonym, meaning to move forward or progress. In the context of actions, it implies promoting or facilitating rather than hindering.

The meanings of the other options are as follows:

Intercede: While it involves intervention, intercede typically implies mediating or pleading on behalf of others, not necessarily in a disruptive manner.

Hamper: This is a synonym for interfere, indicating an obstruction or impediment.

Jam: While it can convey a sense of obstruction, jam is more associated with a physical blockage or congestion.

Therefore, advance is the most appropriate antonym, as it signifies moving forward or progressing without hindrance.
