D. b alone

Answer

To answer the question "Cell is", we need to evaluate the three given statements about the cell:

1. **Cell is a fundamental unit**:
- This statement is correct. Cells are considered the basic building blocks of all living organisms. They are the smallest unit of life that can function independently and perform all necessary life processes.

2. **Cell is a structural unit**:
- This statement is also correct. Cells provide structure to organisms. They group together to form tissues, which then combine to form organs, thus giving shape and support to the organism.

3. **Cell is a functional unit of all living organisms**:
- This statement is correct as well. Cells carry out all the essential functions needed for life, including metabolic processes, growth, and reproduction. They are responsible for the physiological and biochemical activities that sustain life.

Since all three statements about the cell are correct, we conclude that the answer to the question is:

**Correct Answer: All of the above (A, B, and C)**

### Step-by-Step Solution:
1. Identify the statements regarding the cell.
2. Evaluate each statement to determine if it is correct.
