Task: Answer the multiple choice question.
Query: Which compound exhibits a 20.005\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: O=C(O)c1ccc(OC2CSC2)cc1
b: COc1cc(OC)c(NC(=O)C2CCCO2)cc1Cl
c: COC(=O)c1cnn2c1C(=O)N(Cc1cccs1)CC2
d: O=C(NC1CCCCC1)C(c1ccco1)N(C(=O)c1csnn1)c1ccccc1
Answer: c. COC(=O)c1cnn2c1C(=O)N(Cc1cccs1)CC2
