Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 12.214% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] COc1cc(S(=O)(=O)NCCCn2ccnc2)ccc1F
[b] O=c1oc2c(O)cccc2cc1-c1nc2ccccc2[nH]1
[c] COc1cc(C(=O)NCC2CCCCC2)ccc1OCc1c(C)noc1C
Answer: b. O=c1oc2c(O)cccc2cc1-c1nc2ccccc2[nH]1
