Task: Answer the multiple choice question.
Question: Which drug exhibits a -3.309% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. O=C(NCC1CCCCC1)c1cccc(Br)c1
b. Cc1nc2ccccc2n1CCOc1ccccc1
c. CCC(c1nnc(SCC(=O)NCCc2ccc(Cl)cc2Cl)o1)N(C)C
d. COC(C(=O)Nc1ccnn1C1CCN(Cc2ccc(CO)o2)CC1)c1ccccc1
Answer: a. O=C(NCC1CCCCC1)c1cccc(Br)c1
