Option C: 7 hours to build 8 house,
Whenever getting work-time related questions, it is needed to focus that as the amount of work done increases, the time needed to complete also increases.
Given that:
3.5 hours of work is needed to build 4 birdhouses.
Thus as we increase the time twice, the number of birdhouses build by the same person Jasmine will be twice as she got doubletime, thus building 2 times 4 i.e. 8 birdhouses.
Thus we have:
Jasmine takes 7 hours of work to build 8 birdhouses.
Therefore we see that Option C: 7 hours to build 8 birdhouses is correct.
