Task: Answer the multiple-choice question.
Query: Which drug exhibits a 6.153\% 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=C(NCCCN1CCOCC1)c1ccc(Br)cc1
b O=C(Nc1cccc2ccccc12)C1CCN(C(=O)NCc2ccccc2)CC1
c O=[N+]([O-])c1cc(S(=O)(=O)Nc2ccccc2)ccc1NCc1ccccc1
d CCOc1cc(CNc2ccc(N3CCCC3)cc2)cc(Cl)c1OC
Answer: d. CCOc1cc(CNc2ccc(N3CCCC3)cc2)cc(Cl)c1OC
