How can "Can you give me help with this?" be changed to a formal tone?

The option that changes the sentence to a formal tone is "Could you provide me assistance with this?" This formulation employs both "could you," which softens the request compared to "can you," and "provide me assistance," which is a more formal phrasing compared to simply asking for help. The use of "provide" enhances the professionalism of the request, making it suitable for formal interactions.

In contrast, while other options such as "Could you assist me with this?" and "Would you help me with this?" are fairly polite, they do not have the same level of formality as the selected answer. "Can you assist me with this?" retains the original query's informal "can," which lowers the level of formality.
