Explanation:

When the frequency of stimulation is high, a muscle cannot fully relax between twitches, leading to summation and a sustained smooth contraction called tetany. Threshold contraction refers to the minimum - level contraction to cause a response. Latent contraction is not related to the described scenario. Recruitment is about the activation of more motor units.

Answer:

B. high; tetany
