That's true. The mass of your body is like the money
in your pocket. It doesn't change, no matter where you
take it.

I think it should be option (b)
She can climb 0.92 m without losing weight.
<u>Explanation</u>:
Gravitational potential energy is the energy consisting of the product of mass, gravity and height.
1 cal = 4184 J
140 cal = 585760 J
Energy = 585760 J, m = 65.0 kg = 65000 g, Efficiency = 20 %
GPE = mgh
where m represents the mass
g represents the gravity,
h represents the height.
585760 = 65000
9.8
h
h = 0.92 m.
5.16 meters!!!!!!!!!!!!!!!!!!!!
