Answer:
The correct answer would be Exaggeration. We can infer from this story that Frank's grandfather likely engaged in Exaggeration.
Explanation:
When someone tells or describes something in a worse or better way than it actually happened, that person is actually engaging in Exaggeration. So telling something in a superior or inferior way than it really is by someone is exaggeration, and the person who is engaged in exaggeration is said to be exaggerating the situation.
So in this question, when Frank's grandfather go for fishing, he always tell that he caught and released a bigger and bigger fish. He actually exaggerates.
Another similar example of exaggeration can be, if someone says that he caught as bigger fish as his house.
