Task: Answer the multiple-choice question.
Question: Which drug has a -1.186\% 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 additional words.
Options:
(a) COc1ccc(-c2nnc(-c3ccccc3)o2)cc1OC
(b) O=C(O)C(O)c1ccccc1.O=C(O)C(O)c1ccccc1
(c) COc1ccc(NC(=O)/C=C/c2cc(Br)ccc2OC)cc1
(d) CCOC(=O)[C@@H]1CCNC[C@@H]1c1ccccc1.Cl
Answer: a. COc1ccc(-c2nnc(-c3ccccc3)o2)cc1OC
