1. The integer parts of two finite decimals are 7 and 10, respectively. Therefore, the number of possible integer values for the product of these two finite decimals is $(\quad)$.
(A) 16
(B) 17
(C) 18
(D) 19
Parse: Let these two finite decimals be $A$ and $B$, then $7 \times 10=70 < AB < 8 \times 11=88$, it is obvious that the integer part of the product can be any integer from $70$ to $87$, so there are $87-70+1=18$ possible integer parts for the product of these two finite decimals.

Answer is C.
