Options

A. A-p, B-r, C-t, D-q, E-s
B. A-s, B-t, C-q, D-r, E-p
C. A-q, B-r, C-p, D-t, E-s
D. A-t, B-s, C-r, D-q, E-p

Answer

To solve the matching question, we need to analyze each entry in Column I and find the appropriate match in Column II. Here’s the step-by-step solution:

### Step 1: Analyze Entry (A) - German silver and gold jewellery
- **German silver** is an alloy composed of copper, nickel, and zinc.
- **Gold jewellery** is also a mixture of gold and other metals (like silver or copper).
- Both are mixtures of different elements.

**Match:** (A) → (s) Mixtures

### Step 2: Analyze Entry (B) - Antimony and Bismuth
- **Antimony (Sb)** and **Bismuth (Bi)** are both classified as metalloids. They have properties that are intermediate between metals and non-metals.

**Match:** (B) → (t) Metalloids

### Step 3: Analyze Entry (C) - ZnSO₄·7H₂O and FeSO₄·7H₂O
- **ZnSO₄·7H₂O** (Zinc sulfate heptahydrate) and **FeSO₄·7H₂O** (Iron(II) sulfate heptahydrate) have the same composition and crystalline structure, which makes them isomorphs.

**Match:** (C) → (q) Isomorphs

### Step 4: Analyze Entry (D) - Zinc blende and Wurtzite
- **Zinc blende** and **Wurtzite** are two different crystalline forms of zinc sulfide (ZnS). They are examples of polymorphs, where a substance can exist in more than one crystalline form.

**Match:** (D) → (r) Polymorphs

### Step 5: Analyze Entry (E) - Graphite and Diamond
- **Graphite** and **Diamond** are both forms of carbon (C) but have different structures and properties. They are considered different allotropes of the same element.

**Match:** (E) → (p) Elements

### Final Matches:
- (A) → (s) Mixtures
- (B) → (t) Metalloids
- (C) → (q) Isomorphs
- (D) → (r) Polymorphs
- (E) → (p) Elements

### Conclusion:
The correct option that matches all entries is:
**Option (b)**:
- (A) → (s)
- (B) → (t)
- (C) → (q)
- (D) → (r)
- (E) → (p)
