AI Explanation

The correct answer is A) top dead center. On the indicator card shown in the illustration MO-0108, lines 'A' and 'B' indicate the position of the piston at top dead center (TDC). This is the point where the piston reaches its highest position in the cylinder, which is a critical reference point for engine timing and performance. The other answer choices are incorrect because they do not accurately describe the information provided in the illustration.
