Steel Wool Wetted with Vinegar Is Stuffed into a Narrow

Steel wool wetted with vinegar is stuffed into a narrow mouth round glass bottle.A rubber balloon is then sealed over the mouth of the bottle.After several hours,the balloon inflates into the bottle in an inverted manner.What happened?

A) Vinegar fumes are diamagnetic and as they accumulate above the liquid the steel wool is attracted thus inflating the balloon into the mouth of the bottle in an inverted manner.
B) The caustic vinegar fumes get past the steel wool and deteriorate the balloon,which begins to sag into the bottle and inflate it in an inverted manner.
C) The vinegar reacts with the steel wool by absorbing oxygen within the bottle thus decreasing the pressure.The greater outside pressure causes the balloon to inflate in an inverted manner.
D) False! The balloon inflates above the mouth of the bottle because the reaction between the vinegar and steel wool produces a gas which is forced upward because of increased pressure inside the sealed bottle.
