The first alternative is correct (A).
This is an issue that requires you to correlate an affirmation with something that makes logical sense. If the statement says that parents should expose their children to more than one language in childhood, there is an implicit assertion that this is a differential for the development of the child. Thus, alternative (A) seems more appropriate, since it suggests that bilingual students have a greater cognitive ability to solve problems in relation to students who speak only one language. This makes sense since learning more than one language forces the child's brain to deal with more information and with greater communication complexity.
