Task: Answer the multiple choice question.
Question: Which drug exhibits a -1.299\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) COc1ccc(-c2cc(=O)[nH][nH]2)cc1OC
(b) O=C(CNS(=O)(=O)c1ccc(Br)s1)N1CCN(c2ccc(F)cc2)CC1
(c) Cc1[nH]c2ccc(O)cc2c1CCN.O=C([O-])/C=C\C(=O)[O-]
Answer: b. O=C(CNS(=O)(=O)c1ccc(Br)s1)N1CCN(c2ccc(F)cc2)CC1
