Choose A, B, C, or D that best completes each sentence. The International Baccalaureate is also now offered by more schools in the UK as a(n) ______to A-levels. A.  Choice B.  Substitution C.  Alternative D. option

Therefore, option D. option is close in meaning to alternative, but alternative is a more suitable word choice in this context.

Choice (option A) does not accurately describe the relationship between the International Baccalaureate and A-levels. Substitution (option B) implies replacing A-levels entirely, which is not necessarily the case.

The correct answer is C. Alternative. The International Baccalaureate is offered as an alternative to A-levels in more schools in the UK.

More schools in the UK are now offering the International Baccalaureate as an alternative to A-levels.

The International Baccalaureate provides students with another option besides A-levels.
