Explanation:

- Option 1: William Edwards was associated with the East India Company but is not credited as the first Englishman to reach Emperor Jahangir's court.

- Option 2: George Barlow was not an early visitor to Jahangir's court. He was involved in a different era of British-Indian relations.

- Option 3: Thomas Roe was indeed a prominent figure and ambassador to Jahangir's court, but not the first Englishman to visit.

- Option 4: Hawkins is the correct answer. Captain William Hawkins reached Jahangir's court in 1608, marking the first official English presence in the Mughal Empire.
