Task: Answer the multiple choice question.
Query: Which drug has a 4.200\% 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=C(CNC(=O)c1cccs1)NCC(=O)OCc1ccccc1Cl
b COc1ccc(/C=N/NC(=O)c2nnn(-c3nonc3N)c2CN(C)c2ccccc2)cc1
c O=C(OCc1nc2ccsc2c(=O)[nH]1)c1ccc(Cl)s1
d CCNS(=O)(=O)c1ccc(NC(=O)c2ccc(Cn3cc(Br)cn3)o2)cc1
e O=C1CC(Cc2ccccc2)C(=O)N1CCc1ccc2c(c1)OCO2
Answer: c. O=C(OCc1nc2ccsc2c(=O)[nH]1)c1ccc(Cl)s1
