Options

A. 0. 2, 2, 3, 3
B. 2, 2, 3, 3, 3
C. 2,2,3,4, 3
D. 0, 2, 1,2,3

Answer

To determine the digital formula for the hind limbs of a frog, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Digital Formula**:
- The digital formula is a way to represent the number of phalanges (bones) in the digits (fingers or toes) of an animal's limbs. Each number in the formula corresponds to the number of bones in each digit of the limb.

2. **Identify the Structure of Frog Limbs**:
- Frogs have a specific arrangement of bones in their hind limbs. The hind limbs are adapted for jumping and swimming, which influences their bone structure.

3. **Count the Phalanges in Frog Hind Limbs**:
- In frogs, the digital formula for the hind limbs is represented by a series of numbers that indicate the number of bones in each digit:
- The first digit (toe) has 2 phalanges.
- The second digit has 2 phalanges.
- The third digit has 3 phalanges.
- The fourth digit has 4 phalanges.
- The fifth digit has 3 phalanges.

4. **Write the Digital Formula**:
- Based on the phalange counts, the digital formula for the hind limbs of a frog is written as: **2-2-3-4-3**.

5. **Select the Correct Option**:
- From the provided options, the correct digital formula for the hind limbs of a frog is option C: **2-2-3-4-3**.

### Final Answer:
The digital formula for the hind limbs of a frog is **2-2-3-4-3**.
