Task: Answer the multiple-choice question.
Query: Which drug exhibits a -22.845\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. CCOC(=O)C1CCCN(C2=NC(=O)/C(=C/c3ccc(OC)cc3)S2)C1
b. Cc1ccc(Nc2nnc(C3C(=O)N(C)C4(C)CC3c3cc(Br)ccc3O4)s2)cc1
c. O=C(c1ccc(-n2cncn2)c([N+](=O)[O-])c1)N1CCN(S(=O)(=O)c2ccc(Br)cc2)CC1
d. CCN(CC)CCn1c2c(c(SCC(=O)Nc3nc4ccccc4s3)nc1=O)CCC2
Answer: d. CCN(CC)CCn1c2c(c(SCC(=O)Nc3nc4ccccc4s3)nc1=O)CCC2
