Options

A. Acrylic
B. Nylon
C. Polyester
D. Rayon

Explanation

To determine which fiber can be worn comfortably on a hot summer day, we need to analyze the properties of different fibers. Here’s a step-by-step solution:

### Step 1: Identify the fibers
First, we need to identify the types of fibers mentioned in the question. Common fibers include cotton, linen, rayon, polyester, and silk.

### Step 2: Understand the properties of each fiber
Next, we should understand the properties of these fibers:
- **Cotton**: Breathable and absorbs moisture, making it comfortable in hot weather.
- **Linen**: Also breathable and has a cooling effect due to its ability to wick moisture away.
- **Rayon**: Made from plant cellulose, it is breathable and has a cooling effect as it absorbs moisture quickly.
- **Polyester**: Synthetic fiber that does not absorb moisture well and can feel hot and sticky.
- **Silk**: While luxurious, it can be less breathable and may not be as comfortable in extreme heat.

### Step 3: Evaluate the comfort level in hot weather
Now, we evaluate which of these fibers would be most comfortable in hot weather:
- **Cotton and Linen** are both excellent choices due to their breathability and moisture-wicking properties.
- **Rayon** is also a good option as it provides a cooling effect by absorbing moisture quickly.
- **Polyester** is generally not recommended for hot weather due to its poor moisture absorption.
- **Silk** can be comfortable but may not be as effective as cotton or linen.

### Step 4: Conclusion
Based on the properties and comfort levels, **rayon** is a suitable choice for a shirt to be worn on a hot summer day due to its moisture-absorbing capabilities and cooling effect.

### Final Answer
A shirt made of **rayon** can be worn comfortably on a hot summer day.
