- D$-4214$
✓
Answer
Correct option: A.
$4300$
$(-43) \times (-99) + 43$
$= (-1) (43) \times (- 99) + 43$
$= 43 {-(-99) + 1}$ [taking $43$ as common]
$= 43 (99 + 1)$
$= 43 \times 100$
$= 4300$
$= (-1) (43) \times (- 99) + 43$
$= 43 {-(-99) + 1}$ [taking $43$ as common]
$= 43 (99 + 1)$
$= 43 \times 100$
$= 4300$
