Task: Answer the multiple choice question.
Query: Which drug has a 2.221\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a O=C(O)C1C2CCC(O2)C1C(=O)NCCC1=CCCCC1
b O=c1cc[nH]c2c(C(F)(F)F)cccc12
c S=c1[nH]nc(-c2ccc3ccccc3n2)n1-c1ccccc1
d CCCc1nc2c(c(=O)c3ccccc3n2C)c(=O)n1-c1cc(C)cc(C)c1
e COc1cc(Br)cc(/C=N/N(CCO)C2=NS(=O)(=O)c3ccccc32)c1OC
Answer: b. O=c1cc[nH]c2c(C(F)(F)F)cccc12
