1. (10 points) The integer parts of two finite decimals are 7 and 10, respectively. The integer part of the product of these two finite decimals can have ( ) possible values.
A. 16
B. 17
C. 18
D. 19
【Analysis】The integer parts of the two decimals are 7 and 10, respectively, so the minimum integer part of the product of these two decimals is 7 $\times 10=70$; the maximum integer part of the product of these two decimals does not exceed $8 \times 11=88$. Therefore, the integer part of the product of these two decimals is between 70 and 88, including 70, but not including 88, with a total of 18 possibilities. According to this, solve the problem.

【Solution】Solution: According to the problem and analysis:
The minimum integer part of the product of these two decimals is $7 \times 10=70$;
The maximum integer part of the product of these two decimals does not exceed $8 \times 11=88$;
Therefore, the integer part of the product of these two decimals is between 70 and 88, including 70, but not including 88,
There are: $88-70=18$ possibilities;
Answer: The integer part of the product of these two finite decimals has 18 possible values.
Therefore, choose: $C$.
