Technician A says continuous variable transmissions may use two variable diameter pulleys rather than gears to change ratio. Technician B says a hybrid vehicle may use a parallel hybrid transmission, in which either the engine or an electric motor can power the transmission. Which technician is correct?
A) Technician A
B) Technician B
C) Both A and B
D) Neither A nor B

Question

Technician A is correct because continuous variable transmissions (CVTs) often use two variable diameter pulleys connected by a belt or chain to change the transmission ratio smoothly. Technician B is also correct because a parallel hybrid transmission allows either the internal combustion engine or the electric motor to power the vehicle, or both can work together.
