Task: Answer the multiple choice question.
Query: Which compound exhibits a 7.530\% 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 COCCNc1oc(/C=C/c2ccccc2)nc1C#N
b CCn1c(SCC(=O)c2ccc(C)cc2)nnc1-c1ccncc1
c O=C(O)CCCC(=O)N1CCOCCOCCOCCOCC1
d C=CCn1c(Cc2ccc(OC(C)C)c(Cl)c2)nnc1SCC(N)=O
Answer: a. COCCNc1oc(/C=C/c2ccccc2)nc1C#N
