If w,x,y and z are distinct odd positive integers,then the maximum value of the expression (w^2+x^2)*(y^2+z^2) can be divisible by?	Options.
A) 2  B) 3  C) 5  D) 8  E) 10
ANY ODD NUMBER SQUARE WILL GIVE ODD NUMBER ONLY..   SIMILARLY WEN WE ADD 2 ODD NUMBERS WE WILL GET EVEN NUMBER..   WEN WE MULTIPLY 2 EVEN OWE WILL GET EVEN NUBER..   SO THE RESULT OF THE ABOVE EXPRESSION IS AN EVEN NUMBER ONLY..   HENCE IT IS DIVISIBLE BY 2...   2NSWER:2
