2. Disjunctive syllogism deals with the concept that either A or B will be true. Thus, if A is true, B is false and if A is false, B is true.

Here, in all the four options, Rahim and his date will go to either a movie or dinner.

In the first option, dinner gets cancelled and movie gets chosen, thus, a disjunctive syllogism.

In the second option, movie gets chosen and dinner gets cancelled, thus, a disjunctive syllogism.

In the third option, movie gets cancelled and dinner gets chosen, thus, a disjunctive syllogism.

In the fourth option, dinner gets chosen and movie gets cancelled, thus, again a disjunctive syllogism.

Thus, all the four options are examples of disjunctive syllogism and thus, all the above are correct.

Note: We are supposed to answer only one question in case of multiple questions, thus, answering the first question of the lot.
