If the points `((a^3)/((a-1))),(((a^2-3))/((a-1))),((b^3)/(b-1)),(((b^2-3)/((b-1))),` and `(((c^2-3))/((c-1))),` where `a , b , c` are different from 1, lie on the `l x+m y+n=0` , then `a+b+c=-m/l` `a b+b c+c a=n/l` `a b c=((m+n))/l` `a b c-(b c+c a+a b)+3(a+b+c)=0`

A

`a +b +c =-(m)/(l)`

B

`abc = (m +pi)/(l ) `

C

`ab + bc + ca =(n)/(l)`

D

`abc- (ab+bc+ca) + 3 (a+b+c) =0`
