Task: Answer the multiple-choice question.
Query: Which compound exhibits a 2.999\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) Cc1ccc(/C=N/NC(=O)c2nnn(-c3nonc3N)c2C(C)C)o1
(b) C=CCn1c(C)cc(C(=O)CSc2nnc(-c3cccc(S(=O)(=O)N(CC)CC)c3)o2)c1C
(c) CC(C)CSc1n[nH]c(N)n1
(d) CCN(CC(=O)Nc1ccc([N+](=O)[O-])cc1OC)c1ccccc1
Answer: b. C=CCn1c(C)cc(C(=O)CSc2nnc(-c3cccc(S(=O)(=O)N(CC)CC)c3)o2)c1C
