Answer:
b. journal articles
c. experimental data
Explanation:
In any report writing, if any reference is mentioned or quoted in the body of the report, it should be listed in the reference section of the report. Thus while making laboratory report, various information can be used while preparing the report taking help from other sources.
For example, the value of some experimental data such as the value of acceleration due to gravity, electron's mass, Planck's constant, Universal Gas constant, etc. can be used from other sources while making a laboratory report.
Also we take references from various articles of journals to present our content in the report
So these data should be cited in the reference section of the report.
Hence the correct option is (b) and (c).
