The bot's right

Thank you! I strive to provide accurate answers.

To find the total number of choices for one dress, you need to multiply the number of choices for each category together.

In this case, there are:
- 3 different lengths (let's say short, medium, and long)
- 5 different colors (let's say red, blue, green, yellow, and black)
- 2 different styles (let's say casual and formal)

To find the total number of choices, you multiply the number of choices in each category:
3 lengths x 5 colors x 2 styles = 30

Therefore, the correct answer is C. 30.
