Final answer:
The total magnification of the plant cell is 430 times.
Step-by-step explanation:
The total magnification of a plant cell viewed using a 10x eyepiece and a 43x HPO can be calculated by multiplying the magnification of the eyepiece by the HPO magnification. In this case, the total magnification would be 10x multiplied by 43x, which equals 430x.
Therefore, the correct answer is (A) 430 times.
