Based on the Rescorla-Wagner model, if the US intensity is increased in the second phase of conditioning, when Lis added to a previously conditioned T in a blocking experiment, then the A) salience of the T will be so much greater than that of the newly added Lthat the T will continue to accrue all of associative strength, preventing blocking. B) salience of the new L will be so much greater (due to the surprising change of the US) that CS_Lwill rob the T of its acquired associative strength on every subsequent conditioning trial until L has gained all available associative strength C) surprising change in the US will double salience of L, causing it to accrue all of the additional associative strength D) surprising change in the US increases the available associative strength, and thus both Land T will gain additional associative strength and prevent blocking

The Rescorla-Wagner model predicts that an increase in the intensity of the US (unconditioned stimulus) makes more associative strength available. Therefore, both the original conditioned stimulus (T) and the newly added stimulus (L) can gain additional associative strength, preventing the blocking effect where only the first conditioned stimulus would normally block the association of the new stimulus with the unconditioned stimulus.
