Task: Answer the multiple choice question.
Query: Which compound exhibits a 21.840% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) C=CCn1c(O)c(C=NCCCOc2ccc(CC)cc2)c(=O)[nH]c1=S
(b) C=CCCCCCCCCC(=O)N1CCN(c2cc3c(cc2F)c(=O)c(C(=O)O)cn3CC)CC1
(c) Cc1cccc(N2Cc3ccc(Br)cc3C2)c1
Answer: a. C=CCn1c(O)c(C=NCCCOc2ccc(CC)cc2)c(=O)[nH]c1=S
