Task: Answer the multiple choice question.
Query: Which drug has a 17.780\% 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 additional words.
Options:
a. CCc1c(C(=O)Nc2ccc(OC)c(Cl)c2)[nH]c(C)c1C(C)=O
b. COc1ccc(CN2CCSCC2)c(OC)c1C
c. COc1cc2cc(C[C@H](C)O)oc(=O)c2cc1OC
d. Cc1ccc(CCC(=O)Nc2nccs2)o1
Answer: c. COc1cc2cc(C[C@H](C)O)oc(=O)c2cc1OC
