Task: Answer the multiple choice question.
Query: Which drug exhibits a 16.780\% 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(c1cccnc1)N1CCOCC1)c1ccco1
b C=CCn1c(SCC(=O)NC2CCCc3ccccc32)nnc1-c1ccncc1
c COC(=O)C1=C(C)NC(C)=C(C(=O)OC)C1C(=O)OCc1nc2cc(C(=O)OC)ccc2c(=O)[nH]1
d CCN(CC(=O)Nc1ccc2c(c1)OCCO2)C(=O)/C=C/c1ccc(F)cc1
Answer: d. CCN(CC(=O)Nc1ccc2c(c1)OCCO2)C(=O)/C=C/c1ccc(F)cc1
