might not
could not ​

Answer 1

Answer:

should not

Explanation:

the train is running late.we shouldnot reach on time

Answer 2

The train is running late. We might not reach on time.

• As the first sentence suggests that 'the train is running late ' which is in the present continuous tense and the action that is the time of our arrival hasn't yet happened, so there is a probability of chance that they might reach late and that's why 'might not'.
• The other two options 'should not' and 'could not' are more focused on the confirmed case, and so both of them are not fit for this sentence.
