Answer 1

I choose D :)

Step-by-step explanation:

Answer 2

The correct choices are A, B, and F.

totalSeconds ← secondsInDay * 365 * numYears. This choice correctly calculates the total number of seconds by multiplying the number of years, days in a year, and seconds in a day.

totalSeconds ← numYears * 365 * secondsInDay. This choice is also correct and equivalent to Choice A. It correctly multiplies the number of years, days in a year, and seconds in a day.

totalSeconds ← secondsInDay * 365 % numYears. This choice is incorrect because the % operator is the modulus operator, and it doesn't calculate the total number of seconds. It calculates the remainder when dividing by numYears.
