Let's simplify the given expression:

\[
\frac{2.4 \times 10^6}{12 \times 10^2}
\]

### Step 1: Simplify the numerical coefficients:
\[
\frac{2.4}{12} = 0.2
\]

### Step 2: Simplify the powers of 10:
\[
\frac{10^6}{10^2} = 10^{6-2} = 10^4
\]

So, the expression simplifies to:

\[
0.2 \times 10^4
\]

### Step 3: Convert this into proper scientific notation:
To convert \(0.2 \times 10^4\) into scientific notation, we shift the decimal point by one place to the right:

\[
0.2 \times 10^4 = 2 \times 10^3
\]

Thus, the correct answer is:

\[
2 \times 10^3
\]

The correct option from the choices given is **"2 × 10³"**.
