Solve the following question and mark the best possible option.
"TNQ" is an organization imparting training to people to touch the different dimensions of life and be like God. It was planning to organize series of eight lectures A, B, C, D, E, F, G, and H, not necessarily in the same order, for three subjects X, Y, and Z. Subject X was to be covered first in three lectures followed by Z and then subject Y in two lectures. Lectures A, C, and D have to be on separate days. Lectures B and F have to be kept on separate days. Lecture B cannot be clubbed with A or G or D. LecturesG and H should happen on one day.
Which combination of lecturers was arranged on the second day of the series?
Day 1: X = A G H
Day 2: Z = B C E or D E F
Day 3: Y = D F or B C
The triads possible are B C E or D E F
So, Data inadequate is the correct option.
