pls answer with explanation​

Answer 1

Step-by-step explanation:

-a²b²c/2 + ab²c/3 - abc²/4 - ca²b²/5 + cb²a/6 - c²ab/7 + ca²b/8

» -a²b²c/2 - a²b²c/5 + ab²c/3 + ab²c/6 - abc²/4 - abc²/7 + a²cb/8

» -5a²b²c - 2a²b²c/10 + 2ab²c + ab²c/6 - 7abc² - 4abc²/28 + a²cb/8

» -7a²b²c/10 + 3ab²c/6 - 11abc²/28 + a²cb/8

» -7/10a²b²c + 1/2ab²c - 11/28abc² + 1/8a²cb

Hence,

Option B is correct.
