After Several Years of Higher Education,Tom and Zoe Dash Were

After several years of higher education,Tom and Zoe Dash were awarded their Ph.D.degrees and found jobs at an eastern university,where they plan to work in research labs.Tom's lab is very large with at least 15 research faculty like himself and 25 graduate students whose benches are all together on one side of the laboratory.Zoe's lab is similar in size,but graduate student benches are interspersed with faculty.From the very beginning,Tom was referred to as Dr.Dash by the graduate students.Zoe and the graduate students in her lab are on first-name basis.As a student of management,which of the following statements would you consider good advice to the managers also known as the principle investigators) of these labs?

A) Graduate students will easily lose respect for the principle investigator and other faculty if they are not encouraged to use the title: "Dr" when referring to the researchers who have attained the Ph.D.degree
B) There is a lot of sensitive information and highly classified techniques in the research process that should not be shared with graduate students
C) Job enrichment is an important part of the learning process,and it will only happen if students have their own space,separate from the faculty/researchers
D) Open communication occurs when barriers such as work titles and ranks are eliminated,and work spaces are conducive to learning
