Explanation:

• Option A: An open power steering assist fuse would prevent the electric power steering (EPS) system from receiving electrical power. Without power, the EPS cannot assist the driver, resulting in hard steering effort at all times.
• Option B: A mis calibrated steering angle sensor would likely cause issues like incorrect steering feel during turns (e.g., uneven assist during left - right turns) rather than consistent hard steering at all times.
• Option C: A loose engine accessory belt is more related to issues like power steering pump (if it's a hydraulic - assisted system, but for EPS, the main power source is electrical) not getting proper drive. But EPS is electric, so this is less likely.
• Option D: Loose steering column mounting bolts would cause vibrations, noise, or potential misalignment of the steering column, not hard steering effort.

Answer:

A. An open power steering assist fuse
