C. 1-a:2-c,3-d,4-b
D. 1-d:2-a,3-c,4-b

Answer

To solve the problem of matching the technologies in Column A to their related scientific principles in Column B, we will analyze each technology and identify the principle that best corresponds to it.

### Step-by-Step Solution:

1. **Identify the first technology: Steam Engine**
- The steam engine operates based on the principles of thermodynamics, which involve the conversion of heat energy into mechanical work.
- **Match:** 1) Steam engine → b) Thermodynamic laws

2. **Identify the second technology: Nuclear Reactor**
- A nuclear reactor primarily relies on the process of nuclear fission, where the nucleus of an atom splits into smaller parts, releasing a significant amount of energy.
- **Match:** 2) Nuclear Reactor → c) Nuclear Fission

3. **Identify the third technology: Computer**
- Computers operate based on digital logic, which involves the use of binary numbers and logical operations to perform calculations and process data.
- **Match:** 3) Computer → d) Digital logic

4. **Identify the fourth technology: Electric Generation**
- Electric generation typically involves electromagnetic induction, which is the process of generating electric current through the movement of a conductor in a magnetic field.
- **Match:** 4) Electric generation → a) Faraday's laws

### Final Matches:
- 1) Steam engine → b) Thermodynamic laws
- 2) Nuclear Reactor → c) Nuclear Fission
- 3) Computer → d) Digital logic
- 4) Electric generation → a) Faraday's laws
