Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 9.865\% 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. O=C1CC(c2ccccc2)c2cccc(F)c21
b. Brc1nc(Br)n(Cc2ccccc2)n1
c. COCCn1c(C)cc(C(=O)CSc2nc(C)cc(C)c2C#N)c1C
d. CC(NC(=O)CCc1nnc(C2CCCCC2)o1)c1ccc(F)cc1
Answer: a. O=C1CC(c2ccccc2)c2cccc(F)c21
