Match the seientist's name against discovery
A-Scientist B - Discovery
1) Faraday a) Expansion of Universe
2) Newton b) Law of EMI
3) Einstein c) Law of gravitation
4) Hubble d) Theory of relativity

Options

A. 1-b2-c,3-d:4-a
B. 1-b,2-d,3-c,4-a
C. 1-b,2-c:3-a,4-d
D. 1-b2-a,3-c,4-d

Answer

To solve the problem of matching scientists with their respective discoveries, we can follow these steps:

### Step 1: Identify the Discoveries
We have four scientists and four discoveries to match:
1. Faraday
2. Newton
3. Einstein
4. Hubble

The discoveries are:
a) Expansion of Universe
b) Law of EMI (Electromagnetic Induction)
c) Law of gravitation
d) Theory of relativity

### Step 2: Match Each Scientist with Their Discovery
- **Faraday**: Known for his work in electromagnetism, specifically the **Law of Electromagnetic Induction** (EMI). Therefore, we match Faraday with **b**.

- **Newton**: Famous for formulating the **Law of Gravitation**, which describes the gravitational attraction between masses. Thus, we match Newton with **c**.

- **Einstein**: Renowned for his **Theory of Relativity**, which revolutionized our understanding of space and time. Hence, we match Einstein with **d**.

- **Hubble**: Recognized for his work in astronomy, particularly for providing evidence of the **Expansion of the Universe**. Therefore, we match Hubble with **a**.

### Step 3: Write the Final Matches
Now we can summarize the matches:
1) Faraday - b) Law of EMI
2) Newton - c) Law of gravitation
3) Einstein - d) Theory of relativity
4) Hubble - a) Expansion of Universe

### Final Answer:
- 1 - b
- 2 - c
- 3 - d
- 4 - a
