Match the following and identify the correct match.
`{:("The dinosaur Era","In millions of years before "),("a Triassic"," i 175"), ("b Jurassic","ii 225"),("C Cretaceous","iii 125"):}`

Options

A. a-ii, b -i c-iii
B. a-iii, b -i c-ii
C. a-i, b -ii, c-iii
D. a-ii, b - iii, c-i

Answer

To solve the question of matching the dinosaur eras with the corresponding millions of years before present, we will follow these steps:

### Step 1: Understand the Dinosaur Eras
The three periods we need to match are:
1. Triassic
2. Jurassic
3. Cretaceous

These periods are part of the Mesozoic Era, which is known as the age of reptiles.

### Step 2: Identify the Time Frames for Each Period
We need to know the time frames for each of these periods:
- **Triassic Period**: Lasted from approximately 251 to 201 million years ago.
- **Jurassic Period**: Lasted from approximately 201 to 145 million years ago.
- **Cretaceous Period**: Lasted from approximately 145 to 66 million years ago.

### Step 3: Match the Periods with the Given Options
Now, we will match the periods with the options provided:
- **a) Triassic**: This period lasts from 251 to 201 million years ago, so it can be matched with **ii 225 million years ago** (since it falls within this range).
- **b) Jurassic**: This period lasts from 201 to 145 million years ago, so it can be matched with **i 175 million years ago** (since it falls within this range).
- **c) Cretaceous**: This period lasts from 145 to 66 million years ago, so it can be matched with **iii 125 million years ago** (since it falls within this range).

### Step 4: Compile the Matches
Based on the above analysis, we can compile the matches as follows:
- **Triassic** matches with **ii 225 million years ago**.
- **Jurassic** matches with **i 175 million years ago**.
- **Cretaceous** matches with **iii 125 million years ago**.

### Step 5: Identify the Correct Match
The correct matches are:
- a) Triassic - ii 225 million years ago
- b) Jurassic - i 175 million years ago
- c) Cretaceous - iii 125 million years ago

Thus, the correct answer is option **A**.
