( (a, b, d) ) (a) If ( p(x) ) is not divisible by ( g(x), ) then ( r(x) eq 0 therefore(a) ) is not true (b) If ( p(x) ) is divisible by ( g(x) ), then ( r(x)=0 ) for all ( x ) i.e., ( r(x) ) is a zero polynomial whose degree is not defined. ( therefore(b) ) is not true (c) is clearly true [ : division algorithm rule] (d) since degree of ( r(x)< ) degree of ( g(x) ) or ( r(x)=0, ) but ( g(x) eq 0 ) ( therefore r(x)=g(x) ) is not true.
