Stratified and non-keratinised squamous epithelium occurs in
(a) Epidermis of skin
(b) Vagina and cervix
(c) Buccal cavity
(d) Both b and c

Options

A. Epidermis of skin
B. Vagina and cervix
C. Buccal cavity
D. Both (2) and (3)

Answer

To determine where stratified and non-keratinised squamous epithelium occurs, we need to analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Stratified Squamous Epithelium**:
- Stratified squamous epithelium consists of multiple layers of cells. It can be keratinised (with keratin) or non-keratinised (without keratin). Non-keratinised stratified squamous epithelium is found in areas that require protection but also need to remain moist.

2. **Analyzing Option (a): Epidermis of skin**:
- The epidermis of the skin is composed of keratinised stratified squamous epithelium, which provides a protective barrier against environmental damage. Therefore, this option is **incorrect** for non-keratinised stratified squamous epithelium.

3. **Analyzing Option (b): Vagina and cervix**:
- The vagina and cervix are lined with non-keratinised stratified squamous epithelium. This type of epithelium is suitable for these areas as it provides protection while remaining moist. Therefore, this option is **correct**.

4. **Analyzing Option (c): Buccal cavity**:
- The buccal cavity (mouth) is also lined with non-keratinised stratified squamous epithelium. This allows for protection against abrasion while maintaining moisture. Therefore, this option is **correct**.

5. **Analyzing Option (d): Both b and c**:
- Since both the vagina and cervix (option b) and the buccal cavity (option c) contain non-keratinised stratified squamous epithelium, this option is **correct**.

### Conclusion:
The correct answer is **(d) Both b and c**.
