Task: Answer the multiple choice question.
Query: Which drug has a 4.855\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. O=C(NCC(=O)N1CCc2ccccc2C1)c1ccccc1Cl
b. Cc1ccc(S(=O)(=O)N2CCC(C(=O)NCCCN3CCOCC3)CC2)cc1
c. CCOC(=O)c1c(-c2ccccc2)oc2ccc(OCC(N)=O)cc12
d. O=C(CSc1ncnc2c1cnn2-c1ccccc1)Nc1ccccc1
Answer: a. O=C(NCC(=O)N1CCc2ccccc2C1)c1ccccc1Cl
