Hmm, looks like you tripped over your credit card memory here! The correct answer is C. When you "tried" to pay your restaurant bill, you "had forgotten" your credit card at home. Guess it's a case of "No cards, no service!" Next time, remember to bring your plastic buddy along!

The correct answer is C. As per the sentence structure and the use of past tense verbs, the correct option is "C. tried; had forgotten."

The correct answer is C. tried; had forgotten.

To determine the correct answer, let's break down the sentence:

"When I __________ to pay my restaurant bill."

The verb "to pay" is in the past tense, so we need the past tense form of the verb "try." The correct past tense form is "tried."

Now, let's look at the second part of the sentence:

"I realized I __________ my credit card at home."

The verb "to realize" is also in the past tense, so we need the past tense form of the verb "forget." The correct past tense form is "had forgotten."

Therefore, the correct answer is C. tried; had forgotten.
