B. more than that in rabbit
C. double than that of horse
D. less than that in giraffe

Explanation

To answer the question about the cervical vertebrae in humans, we can follow these steps:

### Step 1: Understand the Structure of Cervical Vertebrae
Cervical vertebrae are the bones that make up the neck region of the vertebral column. In mammals, including humans, the number of cervical vertebrae is generally consistent.

### Step 2: Identify the Number of Cervical Vertebrae in Humans
In humans, there are 7 cervical vertebrae. This is a standard number across most mammals, regardless of their size.

### Step 3: Compare with Other Animals
- **Whales**: Like humans, whales are mammals and also have 7 cervical vertebrae.
- **Rabbits**: Rabbits, being mammals as well, also have 7 cervical vertebrae.
- **Horses**: Horses also have 7 cervical vertebrae, similar to humans.
- **Giraffes**: Giraffes, despite their long necks, also possess 7 cervical vertebrae.

### Step 4: Evaluate the Statements
1. The cervical vertebrae in humans is the same as in whales - **Correct**.
2. The cervical vertebrae in humans is more than that in rabbits - **Incorrect** (both have 7).
3. The cervical vertebrae in humans is double that of horses - **Incorrect** (both have 7).
4. The cervical vertebrae in humans is less than that in giraffes - **Incorrect** (both have 7).

### Conclusion
The correct answer is that the cervical vertebrae in humans is the same as in whales.
