Task: Answer the multiple choice question.
Query: Which drug exhibits a 22.408\% 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.) CCOC(=O)c1c(C)c(C(=O)NCc2cccnc2)c(C)n1C
b.) O=C(NCCc1ccccc1)c1ccccc1F
c.) COc1ccc(CC(NC(C)=O)C(=O)NC2CCN(C(=O)c3ccc(OC)c(OC)c3)CC2)cc1OC
d.) O=C(O)CCc1nc(-c2cccs2)no1
Answer: b. O=C(NCCc1ccccc1)c1ccccc1F
