Answer:
7v is a coefficient is correct because a coefficient is a number used to multiply a variable
3u and 4u are like terms is correct because you can add them together regularly but if it was 3u and 4v they would not be like terms
2 is a constant is correct because a constant is a single digit without a variable or a regular number
7v is a factor is correct because factor means a number or numbers that we can multiply together to get another number
7v is a term is correct because in Algebra a term is either a single number or variable, or numbers and variables multiplied together.
none of these are true is incorrect because there are correct answers
Hope this helps
