Step-by-step explanation:
The corrected option is A. We are going to visit Grandpa Mick in Tampa Bay, Florida, next week.
Common nouns refer to general or non-specific people, places, or things, while proper nouns refer to specific names of people, places, or things. In the sentence, 'Grandpa Mick' is a proper noun because it is the specific name of the person being referred to. 'Tampa Bay' and 'Florida' are also proper nouns as they are specific names of a place.
Capitalization is used to distinguish proper nouns from common nouns, so each proper noun should start with a capital letter. The common noun 'grandpa' should not be capitalized unless it is part of a person's name, like 'Grandpa Mick' in this case.
