Reduce thrust - immediate reaction is a slight reduction in pitch due to thrust coupling but maybe they would slow down and recover enough elevator authority to begin a stable climb eventually

Maintain / increase thrust - maybe a slight pitch increase to start with but they will gain speed with limited elevator travel and no chance of overcoming the nose down moment from the stab
Option 1 probably works nicely at when you have altitude on your side...
They had a much easier choice, comply with the QRH for runaway trim, disconnect the trim system, manually trim and fly to destination as airline crews have been doing since the invention of electric trim.
