Task: Answer the multiple choice question.
Question: Which compound has a 3.141\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: Cc1ccccc1-n1nnnc1Sc1nnnn1-c1ccccc1
b: c1ccc(C2CCC(N3CCC(N4CCCCC4)CC3)CC2)cc1
c: O=c1c(Oc2ccccc2Br)c(C(F)(F)F)oc2c(CN3CCCC3)c(O)ccc12
d: O=C(CCCN1C(=O)CCC1=O)Nc1cccc(C(F)(F)F)c1
Answer: c. O=c1c(Oc2ccccc2Br)c(C(F)(F)F)oc2c(CN3CCCC3)c(O)ccc12
