Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 2.057\% 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) O=C(c1cc(-c2cccs2)on1)N1CCc2ccccc2C1
(b) O=C(Nc1cccc(NC(=O)C2C3CC4OC(=O)C2C4C3)c1)c1ccccc1
(c) O=C(CCN1CCCCC1)N/N=C/c1ccc(Br)cc1
(d) CC(=O)Nc1sc(C)c(C)c1C(=O)OCCOc1ccccc1
Answer: a. O=C(c1cc(-c2cccs2)on1)N1CCc2ccccc2C1
