Options

A. Circular
B. Streamlined
C. Elliptical

Explanation

To fill in the blank in the sentence "Cars and speedboats are __________ to reduce drag," we need to identify the appropriate term that describes the design of cars and speedboats that minimizes resistance as they move through air or water.

### Step-by-Step Solution:

1. **Understanding the Context**: The question is about how cars and speedboats are designed to minimize drag. Drag is the resistance experienced by an object moving through a fluid (like air or water).

2. **Identifying the Key Concept**: The key concept here is the design feature that helps reduce drag. This involves the shape and structure of the vehicles.

3. **Finding the Suitable Word**: The term that describes the design of vehicles that helps reduce drag is "streamlined." A streamlined shape allows air or water to flow smoothly over the surface, reducing turbulence and resistance.

4. **Filling in the Blank**: Therefore, the completed sentence is: "Cars and speedboats are **streamlined** to reduce drag."

### Final Answer:
Cars and speedboats are **streamlined** to reduce drag.
