For the binary operation * on `Z` defined by `a*b=a+b+1` the identity element is (a) 0 (b) -1 (c) 1 (d) 2

In the set S=R-{1} under the binary operation o given by a o b=a+b+ab ,the identity element is (a) 1 (b) 0 (c) -1 (d) does not exist

Consider the binary operation on Z defined by a ^(*)b=a-b . Then * is

Binary operation * on R - {-1} defined by a * b= (a)/(b+a)

Binary operation * on R -{-1} defined by a ** b = (a)/(b+1) is
