Problem statement: Answer the multiple choice question.
Query: Which drug has a -8.400\% 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. OCCN(Cc1ccccc1)CC1CC2C=CC1C2
b. CCNC(=O)COc1ccc(/C=C2\COc3ccccc3C2=O)cc1OC
c. COc1ccc(OC)c(C(=O)c2coc3ccc(OCC(=O)O)cc23)c1
d. Cc1ccccc1OCC(=O)NCCCNC(=O)c1cccnc1
Answer: a. OCCN(Cc1ccccc1)CC1CC2C=CC1C2
