Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 4.900\% 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, d, or e without using any additional words.
Options:
(a) O=C(O)c1ccccc1S(=O)CCO
(b) O=[N+]([O-])c1cccnc1NCCNc1ncc(C(F)(F)F)cc1Cl
(c) COc1cccc(C(=O)Nc2ccccc2-c2ccccc2)c1
(d) COc1cc(/C=N/NC(=O)c2cc(-c3ccccc3)nc3ccccc23)cc(OC)c1O
(e) Cc1cc(C(=O)Nc2ccc(F)cc2)c2ccccc2n1
Answer: a. O=C(O)c1ccccc1S(=O)CCO
