The correct option is
E None of these
As per the given information we can organize the lectures as:
Quality circle is on Wednesday, Decision making is on Friday.
Quality Circle cannot be followed by Group Discussion. And there is a gap of two days between Leadership and Group Discussion.
So, GD cannot be organised on Tuesday and Thursday. And hence it will be organised on Monday.
Then Leadership will be on Thursday.
GD is organised before the no lecture day, then Tuesday will be no lecture.
Motivation is organised immediately after Assessment Centre, then Assessment and Motivation will be on Saturday and Sunday respectively.
So, the sequence from Monday to Sunday is :
GD → No lecture → QC → LS → DM → AC → MV.
Clearly, no such pairs of lectures organised on first and last day.
Hence, E is the correct option.
