1. 5|x| + |y| = 0
as we are using absolute values, both x and y >0. however |x| + |y| = 0 only if x=y=0
So we get xy=0 and we can answer the question as NO. Which is an answer on data sufficiency.
So 1 is sufficient
similar logic for 2 and even 2 alone is sufficient
So both alone are sufficient: answer:D
