Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 15.010\% 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, or c without using any additional words.
Options:
a.) CC1=Nn2c(nnc2-c2ccccc2Cl)SC1
b.) NC(=O)NOCc1ccc(F)cc1Cl
c.) COCc1c(C(=O)N/N=C\c2cccnc2)nnn1-c1nonc1N
Answer: b. NC(=O)NOCc1ccc(F)cc1Cl
