Task: Answer the multiple choice question.
Query: Which drug exhibits a 3.488\% 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(O)c1cccc2c1C(=O)c1cccc3snc-2c13
b O=C(CN(Cc1ccccc1)C(=O)c1csnn1)NCc1ccc2c(c1)OCO2
c O=C(NCCc1ccco1)C(=O)NCCC1CCCCN1S(=O)(=O)c1ccccc1
d COc1cc(-c2cc(-c3ccccc3)nc(SCC(=O)O)c2C#N)cc(OC)c1OC
e COc1ccccc1NC(=O)NNC(=O)c1cc2ccccc2cc1O
Answer: c. O=C(NCCc1ccco1)C(=O)NCCC1CCCCN1S(=O)(=O)c1ccccc1
