Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 0.219\% 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: O=C(CSc1nc2c(c(C(F)(F)F)n1)CCc1ccccc1-2)NCc1ccc(F)cc1
b: O=C1COc2ccc(S(=O)(=O)N3CCN(c4ccccc4F)CC3)cc2N1
c: CCNC(=O)CCn1nc(-c2ccc(Cl)cc2)c2ccccc2c1=O
d: CCS(=O)(=O)C1=NN2C(=N)/C(=C\c3ccc(OS(=O)(=O)c4ccccc4)cc3)C(=O)N=C2S1
Answer: c. CCNC(=O)CCn1nc(-c2ccc(Cl)cc2)c2ccccc2c1=O
