Given below are two statements labelled as Assertion (A) and Reason (R):
Select the most appropriate answer from the Options given below:
Assertion (A): Isthmus is the widest part of fallopian tube.
Reason (R): Ampulla is a narrow, terminating part of the Oviduct.

Options

A. Both A and Rare true and R is the correct explanation of A
B. Both A and Rare true but R is not the correct explanation of A
C. A is true but R is false
D. A is false but R is true

Explanation

To analyze the given Assertion (A) and Reason (R), we will evaluate each statement individually and then determine their relationship.

### Step 1: Evaluate the Assertion (A)
**Assertion (A): Isthmus is the widest part of the fallopian tube.**

- The fallopian tube consists of four main parts: the infundibulum, ampulla, isthmus, and interstitial part.
- The isthmus is actually the narrowest part of the fallopian tube, not the widest. The ampulla is generally considered the widest part of the fallopian tube.

**Conclusion for A:** This statement is **False**.

### Step 2: Evaluate the Reason (R)
**Reason (R): Ampulla is a narrow, terminating part of the Oviduct.**

- The ampulla is the widest part of the fallopian tube and is not considered narrow. It is also not the terminating part; the interstitial part is closer to the uterus.
- Therefore, this statement is also **False**.

**Conclusion for R:** This statement is **False**.

### Step 3: Determine the Relationship between A and R
- Since both the Assertion (A) and Reason (R) are false, we need to conclude their relationship.
- The Reason does not explain the Assertion because both statements are incorrect.

### Final Answer
Both Assertion (A) and Reason (R) are false, and the Reason does not provide a correct explanation for the Assertion.
