C Correct answer
Explanation

To pass through the tunnel completely, the train must cover its own length plus the tunnel's length, totaling 6 km (1 km + 5 km). At a speed of 60 kmph, it travels 1 km per minute. Therefore, it takes exactly 6 minutes. Distractors like 5 minutes incorrectly ignore the train's length.
