Task: Answer the multiple choice question.
Query: Which compound has a -4.992% 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 additional words.
Options:
a O=C(NCCc1ccncc1)Nc1ccccc1Cl
b O=C(NCC1(c2ccccc2)CCCC1)c1ccco1
c CCOC(=O)C1=C(CSc2nc(C)cc(C)c2C#N)OC(N)=C(C#N)C1c1cccs1
d Cc1cccc(C)c1NC(=O)C1CCCN1C(=O)NCc1ccccc1
Answer: c. CCOC(=O)C1=C(CSc2nc(C)cc(C)c2C#N)OC(N)=C(C#N)C1c1cccs1
