Step-by-step explanation:

I'm pretty sure its 2 hrs. If she did not take any breaks, she would have made it in 2 hrs due to her taking a 2 hr break. If its not 2 hours,  its 3. But I am 99% sure its 2 hrs.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

so, it becomes,

hence, first option 'a'   is correct.
