Task: Answer the multiple-choice question.
Question: Which drug exhibits a 19.270\% 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.) COc1ccc(-c2cc(-c3ccc(OC)c(OC)c3)n[nH]2)c(O)c1
b.) O=C1CN=C(c2cccc(Br)c2)c2cc(Br)ccc2N1
c.) O=C1[C@H]2[C@H]3[C@H](O)[C@H](O)C/C(=N\OC[C@@H](O)COCc4ccco4)[C@@H]3CC[C@H]2C(=O)N1c1ccc(F)cc1F
Answer: c. O=C1[C@H]2[C@H]3[C@H](O)[C@H](O)C/C(=N\OC[C@@H](O)COCc4ccco4)[C@@H]3CC[C@H]2C(=O)N1c1ccc(F)cc1F
