Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.271\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CCc1nnc(NC(=O)CSc2nnc(C)n2-c2ccc(C)cc2)s1
b: CNCCC(Oc1ccc(C(F)(F)F)cc1)c1ccccc1.Cl
c: Cc1cccc(Cc2nnc(CCC(=O)NCc3cnc4ccccn34)o2)c1
d: COc1ccc(/C=C2\N=C3CCCCCN3C2=O)cc1OC
e: Cn1c(SCC(=O)NCc2ccco2)nnc1-c1cccs1
Answer: a. CCc1nnc(NC(=O)CSc2nnc(C)n2-c2ccc(C)cc2)s1
