a.Both A and B
b.Technician A only
c.Technician B only
d.Neither A nor B

Explicación

The heater core transfers heat from hot engine coolant to cabin air, and a leaking core lets coolant fog the glass and produce a sweet odor. Both technicians are correct. A clogged core or low coolant reduces heat output.
