To multiply the numbers in scientific notation, we multiply the decimal parts and add the exponents.
5.5 * 10 ^ 4 multiplied by 2.2 * 10 ^ -8 can be written as (5.5 * 2.2) * (10 ^ 4 * 10 ^ -8).
Doing the math, 5.5 * 2.2 = 12.1, and 10 ^ 4 * 10 ^ -8 = 10 ^ (4-8) = 10 ^ -4.
Therefore, the answer is 12.1 * 10 ^ -4, which is written in scientific notation as 1.21 * 10 ^ -3.
So, the correct answer is "1.21 * 10 ^ - 3".
