### Explanation of Concepts
1. **Hexadecimal Digits and Nibbles:**
- A **nibble** equals 4 bits.
- Each hexadecimal digit represents exactly 4 bits.
2. **Stack Alignment:**
- Aligning data in memory can be necessary to meet the processor's requirements and improve performance.
- A 32-bit alignment means data is aligned at addresses divisible by 4 bytes.
3. **Stack Memory for int16:**
- An **int16** is a 16-bit integer, meaning it occupies 16 bits in memory when passed by value.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F153bfb9c-b05e-4b91-94e3-9e151aaf7f28%2Fd6f36a9e-a260-4b34-80c1-0ff2ff9c434e%2Fw8xne6q_processed.jpeg&w=3840&q=75)
