Explanation:

In scientific notation, the number before the decimal (the coefficient) must be a number between 1 (inclusive) and 10 (exclusive). So, there should be 1 non - zero digit before the decimal. Wait, looking at the options, maybe there was a typo and the intended correct option is the one with 1 (assuming a formatting error in the options, like maybe the first option was 1). So the correct option is the one with 1 (e.g., if the first option is labeled as, say, A. 1, then A. 1).

Answer:

Assuming the first option is "1" (due to possible formatting in the image), the answer is the option with "1" (e.g., if the first option is A. 1, then A. 1).
