In the question below, few words are given in bold which may not be placed in the correctly. Choose the correct interchange needed between these words to make the sentence grammatically and contextually correct

Developing emotional intelligence helps in (A) building stronger conflicts (B) and managing relationships (C) effectively in professional (D) and personal life.

The correct interchange needed is between the words (B) conflicts and (C) relationships.

Analysis of the original sentence:
In the original sentence, "Developing emotional intelligence helps in building stronger conflicts and managing relationships...", the word choices are contextually incorrect. Developing emotional intelligence is a positive trait, so it should help in building positive things (like relationships) and managing/resolving negative things (like conflicts). One does not aim to "build stronger conflicts" using emotional intelligence.

After interchanging (B) and (C):
The sentence becomes: "Developing emotional intelligence helps in building stronger relationships and managing conflicts effectively in professional and personal life."

This replacement makes the sentence both grammatically correct and contextually logical, as emotional intelligence is key to fostering strong relationships and successfully navigating/managing conflicts.
