Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.460\% 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 additional words.
Options:
a. Cc1n[nH]c(=O)nc1NCc1ccco1
b. Cc1nnc(SCC(=O)Nc2sccc2C#N)n1Cc1ccccc1
c. COc1ccc(NC(=O)CSc2nccn2Cc2ccc(F)cc2)cc1
d. O=C(Nc1ccccc1F)c1cccnc1
Answer: d. O=C(Nc1ccccc1F)c1cccnc1
