AnswerUPSC’s answer is (c).
History has to be on Tuesday. English, Economics and Mathematics must be on three consecutive days in that order, and the only run of three days that avoids Tuesday is Wednesday to Friday. So English is on Wednesday, Economics on Thursday, Mathematics on Friday, and Statistics takes Monday. The Wednesday lecture is English.
Why each option is right or wrong
(a) Wrong. Statistics is on Monday.
(b) Wrong. Economics is on Thursday.
(c) Right. English takes Wednesday.
(d) Wrong. History is on Tuesday.
