An identity card has 4 color schemes and 6 font styles. In how many ways can one color scheme and one font style be chosen?

Answer and explanation

Correct answer: 24 ways

The relevant concept is the multiplication principle of counting. One complete identity-card design requires one color-scheme choice and one font-style choice. There are 4 possible color schemes, and each of them may be combined with any of the 6 font styles. Consequently, the number of distinct color-font pairs is 4 × 6 = 24. Thus option C is correct. The answer 10 comes from adding 4 and 6, which does not enumerate complete designs. The value 18 is another unsupported sum or combination, while 36 is greater than the product and has no stated counting interpretation. Because both choices are required and are independently available, multiplication counts every valid design exactly once.
