Answer :

Rutherford’s Alpha – Particle Scattering Experiment Was Responsible For The Discovery Of

(a) Atomic nucleus

EXPLANATION

Alpha particles are also positively charged particles, so when they were scattered on the gold foil (gold atoms), then most alpha particles were deflected back at large angles, which proved that atoms consists of positively charged particles that are spread in large area and their presence resulted in the repulsion of alpha particles. This large area that consists of positively charged particles was later named as nucleus, which led to the discovery of atomic nucleus.
