The correct statement regarding `RNA` and `DNA`, respectively is `:`

Options

A. The sugar component in RNA is ribose and the sugar component in DNA is 2' -deoxyribose
B. The sugar component in RNA is arabinose and the sugar component in DNA is ribose
C. the sugar component in RNA is 2'-deoxyribose and the sugar component in DNA is arabinose
D. The sugar component in RNA is arabinose and the sugar component in DNA is 2'-deoxyribose

Explanation

To determine the correct statement regarding RNA and DNA, let's analyze the options provided step by step.

### Step 1: Understand the Components of RNA and DNA
- **RNA (Ribonucleic Acid)**: The sugar component in RNA is ribose. Ribose is a five-carbon sugar (pentose) that has an -OH (hydroxyl) group attached to the 2' carbon.
- **DNA (Deoxyribonucleic Acid)**: The sugar component in DNA is 2-deoxyribose. This sugar is similar to ribose but lacks an oxygen atom at the 2' carbon (hence the name "deoxy").

### Step 2: Analyze Each Option
- **Option A**: The sugar component in RNA is ribose, and the sugar component in DNA is 2-deoxyribose.
- This statement is correct based on our understanding from Step 1.

- **Option B**: The sugar component in RNA is arabinose, and the sugar component of DNA is ribose.
- This statement is incorrect because RNA contains ribose, not arabinose.

- **Option C**: The sugar component in RNA is 2-deoxyribose, and the sugar component in DNA is arabinose.
- This statement is incorrect because RNA contains ribose, not 2-deoxyribose.

- **Option D**: The sugar component in RNA is arabinose, and the sugar component in DNA is 2-deoxyribose.
- This statement is incorrect because RNA contains ribose, not arabinose.

### Step 3: Conclusion
After analyzing all the options, we conclude that the correct statement is:
**Option A**: The sugar component in RNA is ribose, and the sugar component in DNA is 2-deoxyribose.
