Options

A. Metamers
B. Positions isomers
C. Metamers as well as position isomers
D. Geometrical isomers

Explanation

To solve the problem regarding the two isomeric alkenes, we will analyze the structures of the given compounds and identify their isomeric relationship step by step.

### Step 1: Identify the Structures of the Alkenes
1. **Alkene (I)**: CH₃-CH=CH-CH₂-CH₂-CH₃
- This structure has a double bond between the second and third carbon atoms when counted from the left.

2. **Alkene (II)**: CH₃-CH₂-CH=CH-CH₂-CH₃
- This structure has a double bond between the third and fourth carbon atoms when counted from the left.

### Step 2: Number the Carbon Atoms
- For **Alkene (I)**:
- Numbering from the left:
- C1: CH₃ (1)
- C2: CH (2)
- C3: CH (3)
- C4: CH₂ (4)
- C5: CH₂ (5)
- C6: CH₃ (6)

- For **Alkene (II)**:
- Numbering from the left:
- C1: CH₃ (1)
- C2: CH₂ (2)
- C3: CH (3)
- C4: CH (4)
- C5: CH₂ (5)
- C6: CH₃ (6)

### Step 3: Determine the Position of the Double Bond
- In **Alkene (I)**, the double bond is located between C2 and C3 (position 2).
- In **Alkene (II)**, the double bond is located between C3 and C4 (position 3).

### Step 4: Identify the Type of Isomerism
- Since the position of the double bond differs between the two alkenes, they are classified as **position isomers**. This means they have the same molecular formula but differ in the location of the double bond.

### Conclusion
The two alkenes are related as **position isomeric alkenes**.

### Final Answer
The two isomeric alkenes are position isomers of each other.
