Task: Answer the multiple choice question.
Query: Which drug exhibits a 5.773\% 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: C=CCc1c(OC)ccc2c1c(S(=O)(=O)c1ccc(C)cc1)cn2COC
b: COc1ccc(Br)cc1/C=C/C(=O)Nc1ccc(C)cc1
c: CCOC(=O)N1CCN(C(=O)c2cnn3c(C(F)F)cc(-c4ccc(C)cc4)nc23)CC1
d: COCCCN(CCNC(=O)c1ccc(NC2=NC3CS(=O)(=O)CC3S2)cc1)Cc1ccco1
Answer: c. CCOC(=O)N1CCN(C(=O)c2cnn3c(C(F)F)cc(-c4ccc(C)cc4)nc23)CC1
