Problem statement: Answer the multiple choice question.
Question: Which drug has a 0.743\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a O=S(=O)(NC(=NC1CCCCC1)c1ccccc1)c1ccc(Cl)cc1
b CC(C)OC(=O)CSc1nnc(-c2cnccn2)n1-c1ccc(Cl)cc1
c COc1cc(O)c(C(CCN2CCCC(C)C2)c2ccc(N(C)C)cc2)c(OC)c1
d N#CCCn1cc(/C=N/NC(=O)c2ccncc2)c(-c2ccc(F)cc2)n1
e O=Cc1ccc2noc(-c3ccc(Cl)cc3)c2c1
Answer: a. O=S(=O)(NC(=NC1CCCCC1)c1ccccc1)c1ccc(Cl)cc1
