The correct answer is: A.Plasmodesmata.

Explanation:

Plasmodesmata are specialized channels that connect plant cells, allowing direct communication and the movement of molecules (such as ions, hormones, and other small signaling molecules) between adjacent cells. These channels enable plant cells to communicate over short distances, coordinating various processes like growth, development, and response to environmental stimuli.

The other options are not used for short-distance communication in plants:

B.Quorum sensing: This is a mechanism of cell communication used primarily by bacteria to se...
