Task: Answer the multiple choice question.
Query: Which compound exhibits a 18.878% 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, c, d, or e without using any additional words.
Options:
a. O=C1c2ccccc2C(=O)N1c1ccc(Cl)cc1
b. O=C(Nc1ccc(S(=O)(=O)N2CCOCC2)cc1)c1ccco1
c. OC1C=CSc2nc3ccccc3n21
d. Cc1cc(O)c(NC(=S)NC(=O)c2ccc(-c3ccc(Cl)cc3)o2)cc1C
e. CCn1c(=O)cc(SCC(=O)NCc2ccccn2)c2ccccc21
Answer: a. O=C1c2ccccc2C(=O)N1c1ccc(Cl)cc1
