Task: Answer the multiple-choice question.
Question: Which drug exhibits a 2.097\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: CC1(C)N=C(N)N=C(N)N1c1ccc(OCCCOc2ccccc2)c(Cl)c1.CCS(=O)(=O)O
b: CC(=O)Nc1ccc(NC(=O)CN(c2ccccc2Cl)S(C)(=O)=O)cc1
c: O=C(CCCCn1c(=O)c2ccccc2n(CC(=O)Nc2cccc(F)c2)c1=O)NCc1ccco1
d: Cc1cc(C)n2nc(C(F)(F)F)c(-c3ccccc3)c2n1
e: O=C(NC(Cc1ccccc1)C(=O)O)/C(=C\c1ccc(Cl)cc1)NC(=O)c1ccco1
Answer: d. Cc1cc(C)n2nc(C(F)(F)F)c(-c3ccccc3)c2n1
