Which energy resource is renewable? A.Coal B.Oil C.Natural Gas D.Wind

All are renewable if you think about it for a minute. Coal is renewed over time although be it a looooooooong time : ), oil is a trickle down effect also renewed over time,just as natural gas is  in the cycle of life during decay and rot, now wind can be renewed  or should I say captured and stored in power storage cells or sold if in excess for others to use,if the wind was not renewed we all would be in serious trouble as the seasons would not change normally(just my guess).now whether man is here to see the coal,natural gas,oil, natural stores being renewed is another question. : )

They are all technically renewable but the answer you are looking for is wind.

Wind is usually considered a renewable energy source, although strictly speaking, it does not renew as such. The others are non-renewing - once you have burned them, that is it, they've gone forever.
