From the options given main wheel spin up is the only reasonable answer. Auto deployment of the spoilers is achieved first by selecting armed, then a function of air ground logic sensors, wheel speed, position of landing gear tilt sensors and throttle position is required to activate the spoilers.

The JAA questions are not type specific and there are normally a number of interlocks that must be operated before the spoilers deploy. For example on the A300 rear main wheel speed must be above 70kts.
