Answer:
The expression is given below as

Concept:
We will have to explain the options so we can figure out what the final answer is
Sum:
The result is obtained by adding numbers
Quotient:
a quotient is a quantity produced by the division of two numbers.
Product:
A product is the result of multiplication,
Factor:
factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder.
Step 1:

We will then have to deal with the parenthesis

We will then have to multiply 7 by 16 before adding to 10
Hence,
7 in the expression above represents a factor because after adding 3 and 13, you would need to multiply 2 and 5. Then, you will multiply 7 and 16 which shows that 7 in the expression above represents a factor. 7 is a factor common to both 3 and 16
Therefore,
The final answer is OPTION A
