Question

Explanation:

Analyze the graph's trend: it shows a continuous upward curve with no flat (constant) or downward segments, and the slope changes so the rate is not uniform.

• Option A is wrong: the rate of increase is not the same (slope varies).
• Option B is wrong: consumption never decreases.
• Option C is wrong: consumption never stays constant.
• Option D is correct: consumption rises continuously over the 12 months.

Answer:

D. Martin's electricity consumption kept increasing continuously throughout the period.
