Brief Explanations:

Conduction is the transfer of heat energy through direct contact. Here, the spoon and boiling - water are in direct contact, and heat is transferred from the hot water to the spoon. Radiation is the transfer of heat through electromagnetic waves, and convection is the transfer of heat through the movement of fluids. Connection is not a heat - transfer mechanism in this context.

Answer:

B. Conduction
