To solve this, we need to line up the numbers and multiply each digit by the digit in the other number’s one’s place, then by its ten’s place, then by its hundred’s place, and so on. We add up the results of each multiplication to get the final answer. Writing this out, we get:

784
× 357
–––––
    2208 (8 x 7)
  3136 (8 x 5, plus 8 x 5 with a carryover of 3)
+ 2352 (4 x 7, plus 2 x 7 with a carryover of 3, plus 3 x 3)
––––––
 279888 (4 x 5, plus 3 x 7 with a carryover of 4, plus 7 x 3 with a carryover of 4, plus 2 x 3)

Therefore, the best choice is D) 279,888.
