Answer:
The sentence that best uses a split infinitive to create emphasis is - Young drivers must remember to fully focus on driving when they get behind the wheel. The correct option is Option B.
Explanation:
A grammatical construction where a word/phrase is put in between ‘to’ and the ‘bare’ infinitive of the ‘to’ form of the infinitive verb. Mostly, an adverb/adverbial phrase comes between the to and the verb.
In other words, a split infinitive happens when an adverb comes in between two parts of an infinitive. In the sentence mentioned above, the same happens. The split infinitive is seen between the ‘to’ and the verb ‘driving.’
