Study the following information carefully and answer the given questions :
A Business School with six Professors L, M, N, O, P and Q has decided to implement a new scheme of course management. Each Professor has to co-ordinate one course and support another course. This semester, O's support course is Finance, while three others have it in co-ordinator's role. P and Q have Marketing as one of their subjects. Q co-ordinates Operations, which is a support course for both N and P. Finance and IT are L's subjects. Both L and O have same subjects. Strategy is a support course for only one of the Professors.
Who among the following are co-ordinating the Finance course?

Options

A. L and N
B. N and O
C. L, M and N
D. M, N and O

Answer

C

Explanation

According to the given information:
`O overset("Support course")rarr` Finance.
So, `O overset("Co-ordiantes")rarr` IT.
[`because La nd O` have the same subjects]
`N overset("Support course")rarr` Operations.
`P overset("Support course")rarr` Operations.
`Q overset("Co-ordiantes")rarr` Operations
So, `P overset("Co-ordinates")rarr` Marketing
[`because` P and Q have Marketing as one of their subjects]
`Q overset("Support course")rarr` Marketing
By elimination, we get
L, M and N `overset(Co-ordinates")rarr` IT.
`M overset("Support course")rarr` Strategy.

By analysing the above table, we get L M and N `overset("Co-ordinate")rarr` Finance course.
