Technician A is correct that convection can occur in liquids and gases. This is because convection is the transfer of heat through the movement of fluids (liquids and gases) caused by differences in temperature and density.
Technician B is also correct that conduction can occur between two substances that are at different temperatures. Conduction is the transfer of heat through a material or between two materials in contact with each other caused by differences in temperature.
