Correct Answer - Option 3 : At least one discontinued show was a drama
Ten new T.V shows in January: 5 sitcoms, 3 drama and 2 news magazines.
By April: Seven of the new shows were on, five of them are sitcoms.
Here, it can be concluded that 2 shows that were on can be:
Case 1: 2 dramas
Case 2: 1 drama and 1 news magazine show
Case 3: 2 news magazines show.
Here, in all three cases, at least one drama show will be discontinued.
Options 1 and 2 are only possibilities and hence ruled out.
Option 4 can be ruled out because the reason for the closure of the other shows cannot be deduced from the given information.
Hence, 'At least one discontinued show was a drama' is the correct answer.
