D Correct answer
Explanation

The past continuous tense 'were waiting' is correct here because it describes an action in progress at a specific moment in the past. 'At ten o'clock yesterday morning' specifies a particular past time when the waiting was happening. 'Was waiting' would be singular, but 'we' requires plural.
