Jofra Archer, the England fast bowler, is than accurate.

The correct option is more fast.

Explanation:
In English grammar, we typically form the comparative of one-syllable adjectives by adding the suffix -er (for example, "faster"). However, a specific rule applies when we are comparing two different qualities or attributes of the same person or object rather than comparing two different entities.
When comparing two qualities of the same subject (Quality A vs. Quality B), we use the structure "more + adjective" instead of the -er comparative form, regardless of the syllable count of the first adjective.

In this sentence:
- We are comparing two qualities of Jofra Archer: his speed ("fast") and his precision ("accurate").
- Since we are comparing these two traits of the same person, we use "more fast than accurate" rather than "faster than accurate."
- Therefore, "more fast" is the grammatically correct choice to complete the sentence: "Jofra Archer, the England fast bowler, is more fast than accurate."
