Answer: B

Explanation:

(A) In a nonreactive NST, the criteria for reactivity are not met.

(B) A reactive NST shows at least two accelerations of FHR with fetal movements, each 15 bpm, lasting 15 seconds or more, over 20 minutes. (C, D) This term is used to interpret a contraction stress test (CST), or oxytocin challenge test, not an NST.
