Task: Answer the multiple-choice question.
Question: Which drug has a 21.467\% 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, or c without using any additional words.
Options:
a: CCOc1ccc(OCC)c(-c2c(=O)n(OCc3ccc(C(C)(C)C)cc3)c3ccccc3[n+]2[O-])c1
b: O=C(Cc1ccc(F)cc1)N1CCC(CC2CC(c3ccc(Cl)cc3)=NO2)(C(=O)NCC2CCCCC2)CC1
c: O=C(OCc1cc(=O)n2c(n1)sc1ccccc12)c1ccc2c(=O)n3c(nc2c1)CCC3
Answer: a. CCOc1ccc(OCC)c(-c2c(=O)n(OCc3ccc(C(C)(C)C)cc3)c3ccccc3[n+]2[O-])c1
