Answer the following question given this paragraph: 

Cells that are communicating may be right next to each other or far apart. In juxtacrine signaling , also known as contact-dependent signaling, two adjacent cells must make physical contact in order to communicate. Cell communication may also occur over short distances, which is known as paracrine signaling , or over large distances, which is known as endocrine signaling .


Q: Cell communication that occurs over short distances is known as what?

 Choices:

- hypersignaling

- contraposition signaling

- cell echo

- paracrine signaling

A:
paracrine signaling
