I'm not entirely sure, however, since no one has answered your question yet, I'll say A. Mobility

This thing probably moves around, and it doesn't look like it could protect it, or anything.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

it would lead to upper respiratory infections and pneumonia.
