The correct answer to this question is : C) Conduction
EXPLANATION:
Before coming into any conclusion, first we have to understand conduction.
Conduction is the mode of transmission of heat in which heat will flow from a body at high temperature to a body at low temperature in contact or from hotter part of the body to its colder part, without any actual transport of particles.
As per the question, the heat is transferred to driver's hand when he touches the steering wheel.
As there is actual contact between hand and steering wheel, the heat transmission will be conduction.
