A

The probability amplitude determines the exact position of the particle.

B

The probability amplitude can cancel out or enhance, leading to interference patterns.

C

The state vector has no effect on the interference pattern.

D

Quantum interference is solely based on classical probabilities.

Understanding the Answer

Let's break down why this is correct

The probability amplitude is a wave‑like number. Other options are incorrect because People think the amplitude tells you exactly where the particle will land; Some think the state vector is irrelevant to interference.
