To write 74,000 in scientific notation, you follow these steps:

1. Move the decimal point in 74,000 so that the number is between 1 and 10. In this case, moving the decimal 4 places to the left gives 7.4.
   
2. Count how many places you moved the decimal. Since you moved it 4 places to the left, this will be the exponent on 10.

Therefore, 74,000 in scientific notation is \( 7.4 \times 10^4 \).

The correct answer is **C. \( 7.4 \times 10^4 \)**.
