Task: Answer the multiple choice question.
Query: Which drug has a 1.664\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=C1c2ccccc2C(=O)N1CCCOc1ccccc1
b: O=C(CN1CCN(c2ccc(F)cc2)CC1)NCC1CCCO1
c: COCCNC(=O)/C=C/c1c(Cl)cccc1Cl
Answer: b. O=C(CN1CCN(c2ccc(F)cc2)CC1)NCC1CCCO1
