The prime factorization of 84 can be determined by breaking it down:

1. Start by dividing 84 by 2, the smallest prime number:
- \(84 \div 2 = 42\)
2. Divide 42 by 2 again:
- \(42 \div 2 = 21\)
3. Now divide 21 by 3:
- \(21 \div 3 = 7\)
4. Finally, 7 is a prime number.

So, the complete prime factorization of 84 is:
\(2^2 \times 3^1 \times 7^1\).

Expressing it with exponents, the answer is:
**\(2^2 \cdot 3^1 \cdot 7\)**.

Among the responses provided, the correct one is:
**\(2^2 \cdot 3 \cdot 7\)**.
