Task: Answer the multiple choice question.
Query: Which drug exhibits a -5.056% 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, or d without using any other words.
Options:
a CCOC(=O)Cn1c(=O)c2c(nc(Br)n2Cc2ccccc2Cl)n(C)c1=O
b CC(C)(C)NC(=O)CSc1nnc(NC(=O)CCn2cnc3ccccc3c2=O)s1
c O=C(OCC(=O)c1cccs1)c1ccccc1
d O=C(c1cc(-c2ccc(Cl)cc2)on1)N1CCOCC1
Answer: c. O=C(OCC(=O)c1cccs1)c1ccccc1
