Identify the correct statement If `a ,b ,c` are odd integers `(a) a+b+c` cannot be zero (b) If `a ,b ,c` are odd integers `a^2+b^2-c^2!=0` (c) If `a^2+b^2-c^2` , then the least one of `a ,b ,c` is even, given that `a ,b ,c` are integers (d) If `a^2+b^2=c^2w h e r ea ,b ,c` are integers then `c > a+b`
