Bhad left
Chas left
Dwill leave
Answer:
B. had left
Read Explanation:
This sentence describes two past actions:
The train's departure.
His arrival at the railway station.
The phrase "when he reached the railway station" indicates that his arrival is a past event. For the train's departure, we need a tense that shows an action completed before another action in the past. This is the function of the Past Perfect Tense.
Past Perfect Tense (had + past participle): Used for an action that was completed before another action or point in time in the past.
Simple Past Tense (reached): Used for the second action that happened in the past.
Here, the train leaving happened before he reached the station, so "had left" is the correct choice.
