Answer 2

Your answer is B they all transfer energy because light energy transfers energy by hitting a solar panel and turning it to electrical energy moving objects transfer energy by when its not moving potential energy and when it is moving its kinetic energy and heat flow transfers energy by conduction on a spoon also its not A because light travels more faster than anything in the world its not C because C requires electrical current an although heat and light can be turned into electrical energy moving objects can't when its came down to rather B, and D I choose B because D has mechanical energy and mechanical energy is made by like paper burning into ashes or a apple rotting and none of them change substances so your answer is B.
