[A]: The DNA fingerprinting relies on recombinant DNA technology and can prove the identification of a suspect.
[R]: It is based on the pattern, length, and· number of DNA repeats and are unique.for each individual's genetic blueprint-DNA
a) If both A and R are true and R is the correct explanation of A
b) If both A and R are true but R is not the correct explanation of A
c) If A is true and R is false
d) If both A and R are false

Options

A. If both A and R are true and R is the correct explanation of A
B. If both A and R are true but R is not the correct explanation of A
C. If A is true and R is false
D. If both A and R are false

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion (A):** The assertion states that DNA fingerprinting relies on recombinant DNA technology and can prove the identification of a suspect. This statement is true. DNA fingerprinting is indeed based on recombinant DNA technology, which allows for the analysis of specific DNA sequences that can identify individuals.

2. **Understanding the Reason (R):** The reason states that DNA fingerprinting is based on the pattern, length, and number of DNA repeats, which are unique to each individual's genetic blueprint. This statement is also true. DNA fingerprinting primarily utilizes repetitive DNA sequences, particularly short tandem repeats (STRs), which vary among individuals (except for identical twins).

3. **Evaluating the Relationship Between A and R:** Since both A and R are true, we need to determine if R correctly explains A. The reason R explains how DNA fingerprinting works and why it can identify individuals, thus providing a correct explanation of the assertion A.

4. **Conclusion:** Both the assertion and the reason are true, and the reason is the correct explanation of the assertion. Therefore, the correct answer is:
**a) If both A and R are true and R is the correct explanation of A.**
