Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 14.505\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a S=P(N1CC1)(N1CC1)N1CC1
b CN(C)c1ccc(/C=N/NC(=O)c2ccccn2)cc1
c COc1ccc(CNC(=O)COC(=O)CCc2nc3ccccc3c(=O)[nH]2)cc1
d COc1cc(/C=C/c2noc(-c3ccccc3O)n2)cc(OC)c1OC
Answer: a. S=P(N1CC1)(N1CC1)N1CC1
