The Contact of a Water Drop on the Hand Can

The contact of a water drop on the hand can be sensed about half a second before its temperature because:

A) Signals in the lemniscal pathway travel more slowly than those in the spinothalamic pathway
B) Signals in the spinothalamic pathway travel more slowly than those in the lemniscal pathway
C) Temperature signals are delayed by a relay to the thalamus
D) Temperature signals are delayed by a relay in the spinal cord
