Answer:
B
Explanation:
Because a product in math means an answer that involves multiplication.
D would of been wrong since the statement mentioned the sum, and it also makes no sense.
A would have been also wrong because there's no equals sign and it's an expression, so there's no total
C would be wrong too, because it says 2 and 3 and 9. By my logic on this part of the question, it would look like this: 2×3×9.
So that leaves answer B.
