C Correct answer
Explanation

The sequence of events requires past perfect tense for the earlier action. 'Had left' shows the train's departure occurred before 'I reached' (simple past). This is a classic case of past perfect for the earlier of two past actions. 'Is leaving' is present continuous, 'has been leaving' is present perfect continuous, and 'has left' is present perfect - all incorrect for this sequence.
