If UVW= 1 , WXY = 0 , and UWX = 0, which of the following must be zero?	Choose the correct choice from the following options: A) U B) V C) W D) X E) Y
UVW= 1 which means neither U / V/ W is 0   W x XY = 0 , we know W is not 0 from above hence either X or Y must be 0.   X x U x W = 0, we know from first expression that U and W are not 0 hence X =0.   OPTION X
<result>D</result>
