Task: Answer the multiple-choice question.
Query: Which drug exhibits a 1.956\% human ether-à-go-go related gene (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: CCOc1ccc(S(=O)(=O)Nc2ccc(C(=O)NCc3ccncc3)cc2)cc1
b: O=C1C=C(NCc2ccco2)C2(CCCCC2)O1
c: C(=N/Nc1ccc2ccccc2n1)\c1ccc2c(c1)OCCO2
d: CC1=C(C(=O)N(C)C)C(c2ccccc2OC(F)F)NC(=O)N1
Answer: a. CCOc1ccc(S(=O)(=O)Nc2ccc(C(=O)NCc3ccncc3)cc2)cc1
