The correct answer is "The objects have the same temperature."
If two objects are in thermal equilibrium both will have the same temperature. Heat flows from a hot to a cold body. Only in the absence of a thermal equilibrium, heat will flow from a body at a high temperature to a body at low temperature. As heat keeps flowing between the hot and cold bodies, finally both will achieve the same final temperature. This is when the two bodies are at thermal equilibrium .
A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds.
