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 their corresponding millions of years before present, we will follow these steps:

### Step 1: Understand the Time Periods
We need to identify the time spans for each of the three periods: Triassic, Jurassic, and Cretaceous.

- **Triassic Period**: This period lasted from approximately 252 million years ago to 201 million years ago.
- **Jurassic Period**: This period lasted from approximately 199 million years ago to 145 million years ago.
- **Cretaceous Period**: This period lasted from approximately 145 million years ago to 66 million years ago.

### Step 2: Determine the Correct Matches
Now, we will match each period with the correct millions of years before present:

- **Triassic (A)**: The end of the Triassic period is around 201 million years ago. So, it corresponds to **ii 225 million years ago** (since 225 million years ago is before 201 million years ago).
- **Jurassic (B)**: The end of the Jurassic period is around 145 million years ago. Therefore, it corresponds to **i 175 million years ago** (since 175 million years ago is before 145 million years ago).
- **Cretaceous (C)**: The end of the Cretaceous period is around 66 million years ago. Thus, it corresponds to **iii 125 million years ago** (since 125 million years ago is before 66 million years ago).

### Step 3: Write Down the Matches
Based on the above analysis, we can summarize the matches as follows:

- **A (Triassic)** → **ii (225 million years ago)**
- **B (Jurassic)** → **i (175 million years ago)**
- **C (Cretaceous)** → **iii (125 million years ago)**

### Step 4: Identify the Correct Match
The correct matches are:
- A → ii
- B → i
- C → iii

### Final Answer
The correct match is:
- A (Triassic) → ii (225 million years ago)
- B (Jurassic) → i (175 million years ago)
- C (Cretaceous) → iii (125 million years ago)
