Task: Answer the multiple choice question.
Query: Which drug exhibits a -8.480\% 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 Cc1cccn2c(=O)c3cc(C#N)c(=O)n(-c4c(C)n(C)n(-c5ccccc5)c4=O)c3nc12
b CCOc1ccc(N(CC(=O)Nc2ccc(F)c(F)c2)S(=O)(=O)c2c(C)noc2C)cc1
c O=C(CSc1nccn1-c1ccc(Cl)cc1)Nc1ccc2c(c1)OCO2
d CCOC(=O)c1sc(C)c2c1NC1(CCCCC1)NC2=O
Answer: d. CCOC(=O)c1sc(C)c2c1NC1(CCCCC1)NC2=O
