10. The correct answer is D.

The original sentence contains several errors. First, the expression

"rather than" requires parallelism, but the original sentence pairs an

active verb ("accept") with a passive one ("was sent"). Second, "if"

is incorrect when used as a synonym for "whether".

The only answer choice to remedy both issues without creating any

new ones is D. Note that "instead of" is incorrect when used with

verbs. For example, "I want to swim instead of dance" is

incorrect. It should be "I want to swim rather than dance."
