Task: Answer the multiple choice question.
Question: Which drug exhibits a 7.805\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) O=C(Nc1ccccc1N1CCCCC1)c1cnccn1
b) C=C(C)C(=O)Nc1cccc(C2=NOC3(C2)C[C@@H](C(N)=O)N(C(=O)[C@H]2CCC(=O)N2)C3)c1
c) COc1ccc(OCc2nnc(SCC(=O)Nc3ccc(C)cc3)o2)cc1
d) CS(=O)(=O)N1CCN(C(=O)c2c(F)cccc2F)CC1
Answer: a. O=C(Nc1ccccc1N1CCCCC1)c1cnccn1
