Option B) A chemical signal is transmitted between the cells of two organisms.

Explanation:

Intercellular communication is the communication which means the transfer of information from one cell to another. Cells signals each other by direct contact or they release a substance or a chemical that is taken up by another cell and transferred to the desired location.

If a hormone travels through the circulatory system to deliver a signal then in that case hormone is released by a cell and is transferred by cells to the required region, hence it is intercellular communication.If  a molecule released from one cell signals one near,but not directly adjacent this can be achieved by different chemicals(Acetylchlorine in case of nerve cell), hence it is intercellular communication.A white blood cell is a single cell produces antibody in itself and hence it is a intercellular communication.

Result: Option B) is incorrect, all other options are correct.

B. nuclear reactions could first occur.
