Options

A. smell
B. hearing
C. respiration
D. touch

Explanation

To solve the question regarding the association of sensory papillae in frogs, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Function of Sensory Papillae**:
- Sensory papillae are specialized structures found in various organisms, including frogs. They play a crucial role in detecting different types of sensory stimuli.

2. **Identify the Types of Sensory Stimuli in Frogs**:
- Frogs have various sense organs that help them detect stimuli such as taste, touch, smell, vision, and hearing.

3. **Link Sensory Papillae to Sensory Functions**:
- Among the various sensory functions, sensory papillae are specifically associated with the sense of touch. They help frogs detect tactile sensations.

4. **Eliminate Other Options**:
- The other options provided in the question are smell, hearing, and respiration.
- Smell is associated with the nasal epithelium.
- Hearing is associated with the tympanum and internal ear.
- Respiration is not directly linked to sensory papillae.
- Therefore, these options can be eliminated.

5. **Conclude with the Correct Answer**:
- Since sensory papillae are primarily involved in detecting touch sensations, the correct answer to the question is **touch**.

### Final Answer:
The sensory papillae in frogs are associated with **touch**.
