Qubit in superposition

Question: What happens when a qubit in superposition is measured? A) It remains in superposition forever B) It collapses to one classical outcome based on probability amplitudes C) It automatically becomes entangled D) It changes into a qutrit Correct: B Explanation: Measurement converts a quantum state into a classical outcome. A qubit in superposition does not reveal both states at once; instead, it produces one result, such as 0 or 1, according to the probabilities determined by its amplitudes.
