Hi Riya,

The problem with option E is that there is a subject verb disagreement. Anomalies was is incorrect. Anomalies were is the correct construction

Why is option A correct in that case? – In option A, the “it” is a placeholder pronoun and acts as the subject here.

It is X that led to Y is an accepted construction. Ask yourself “What led to the discovery of Neptune”. The answer is some fact led to it. The fact has to be referred to as singular.

Hope this helps!
