Let's solve this step-by-step:
1. First, understand what the phrase "the product of 11 and Carlos's age" means. In mathematical terms, "product" refers to the result of multiplying two or more numbers together. This means we should multiply 11 (a constant) with Carlos's age (C). This can be represented as "11C" or "11 times C".
2. The next part of the phrase is "Two less than ...". "Less than" indicates subtraction. So, this means we should subtract 2 from the result of the multiplication we just discussed.
3. Adding these two parts together, the whole phrase "Two less than the product of 11 and Carlos's age" should mathematically be represented as "11C - 2".
In conclusion, the correct answer is a) "11C - 2", which is a mathematical expression representing "Two less than the product of 11 and Carlos's age".
