Answer:
We c)did tell you how to find our house.
Step-by-step explanation:
The emphatic tenses recieve this name because they are used for emphasis. The present emphatic tense is formed by combining the basic present form of the verb to the present tense of the verb to do(do or does.) The past emphatic combines the basic present form of the verb to the past tense of the verb to do(did.) In this case, the past emphatic is used to complete the sentence.
