Alkynes `(A)` and `(B)` have the molecular formula `C_(8)H_(14)` giving following reactions:
(A) or (B) `overset(H_(2)//Pt)rarr "n-Octane"`.
`(A) overset(O_(3)//H_(2)O)rarr CH_(3)CH_(2)CH_(2)CO_(2)H`
(B) `overset(Ag(NH_(3))_(2)OH)rarr` silver containing white ppt.
Write the structure of `(A)` and `(B)`.

Explanation

To solve the problem, we need to identify the structures of alkynes (A) and (B) based on the given reactions and the molecular formula \( C_8H_{14} \).

### Step 1: Analyze the Molecular Formula
Both alkynes (A) and (B) have the molecular formula \( C_8H_{14} \). This indicates that they are both unsaturated hydrocarbons with at least one triple bond.

**Hint:** Look for the degree of unsaturation using the formula \( \text{Degree of Unsaturation} = \frac{(2C + 2 - H)}{2} \).

### Step 2: Identify the Product of Hydrogenation
