Answer:
Option number 2 is correct. When you talk together in a group during a laboratory exercise, you are engaging in classroom scientific communication.
Explanation:
Any type of communication that is made regarding science is described as a scientific communication. This kind of communication generally involves talks about research, recent advances in any scientific topics or techniques, observations that one might have made on a particular science topic, asking another person about any science-related topic or techniques, etc. 
If a scientist talks about any science topic to the public, then it would be a public scientific communication. A scientific communication made among scientists would be termed as professional scientific communication. Any science based communication that is made and kept private would be termed as private scientific communication. 
Hence, option 2 is correct. A science based communication between students in a lab would be classroom scientific communication.
