Task: Answer the multiple-choice question.
Question: Which drug exhibits a 26.811\% human ether-à-go-go related gene (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=C1C=C(N2CCOCC2)CC(c2ccccc2)C1
b. CCc1cc(=O)oc2cc(OCC(=O)NCCCn3ccnc3)ccc12
c. Cl.O=C(OCCCN1CCCC1)C(O)(c1ccccc1)C1CCCCC1
d. CC(C)C[C@H]1CN=C(Nc2ccccc2)N1CC1CCCCCC1
Answer: c. Cl.O=C(OCCCN1CCCC1)C(O)(c1ccccc1)C1CCCCC1
