Problem statement: Answer the multiple-choice question.
Question: Which drug has a 13.253\% 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 other words.
Options:
[a] O=C(Nc1ccccc1Oc1cccnc1)C1CCCN(C/C=C/c2ccccc2)C1
[b] O=C(c1ccc(COc2ccccc2Br)o1)N1N=C(C(F)F)CC1(O)C(F)F
[c] COc1ccc(C(=O)N2CCOCC2)cc1Br
Answer: b. O=C(c1ccc(COc2ccccc2Br)o1)N1N=C(C(F)F)CC1(O)C(F)F
