Answer Details

The word opposite in meaning to "compulsory" is "optional". "Compulsory" means required or mandatory, while "optional" means not required or not mandatory. In the context of the sentence, the students were advised to register for all the required subjects before considering any other subjects that were not required. Therefore, the opposite of "compulsory" would be "optional", which means that the students have a choice whether or not to take those subjects. Option A, "unimportant", may describe some optional subjects, but not all of them. Option B, "optional", is the correct answer because it is the opposite of "compulsory". Option C, "easy", has no relation to the meaning of "compulsory". Option D, "fundamental", describes something that is essential or necessary, which is similar in meaning to "compulsory". Option E, "negligible", means something that is unimportant or insignificant, which is not the opposite of "compulsory". In summary, the correct answer is "optional" because it is the opposite of "compulsory".
