Which is true of intercellular organisms signals do not go through direct connections between cells, such as gap junctions (a. they either match up with a receptor molecule on the surface of the cell or enter the cell through the membrane) (b. the carbohydrate tag is interpreted in the ribosomes, and the signal is passed on to the nucleus of the cell) (c. they connect with another cell partm such as the golgi apparatus, where hormones interpret the signal) (d. they connect with an adjacent cell where an ion linked receptor carries them into the nucleus)

The correct option is this: THEY EITHER MATCH UP WITH A RECEPTOR MOLECULE ON THE SURFACE OF THE CELL OR ENTER THE CELL THROUGH THE MEMBRANE.
Intercellular communicatiion between cells occur in several ways, one of these is through the use of chemical signals. The cell membrane is a semi permeable structure and only allow the passage of specific substances. If the cell membrane allows the chemical signal to pass through, then the signal will enter the cell through the cell membrane. If the cell membrane is not permeable to the chemical signal, the signal can be transported into the cell by means of carrier proteins which are found on the surface of the cell membrane.
