Task: Answer the multiple choice question.
Question: Which drug exhibits a -48.030% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] COC(=O)c1cc(S(=O)(=O)N2CCCCC2)ccc1N1CCOCC1
[b] O=C(CCN1CCN(Cc2ccccc2)CC1)NNC(=O)Nc1cccc([N+](=O)[O-])c1
[c] COc1ccc(CCNC(=O)C23CN(Cc4ccccc4)CC2C(c2ccc([N+](=O)[O-])cc2)=NO3)cc1
[d] O=C(NC(=S)Nc1ccccc1Cl)c1cncc(Br)c1
Answer: a. COC(=O)c1cc(S(=O)(=O)N2CCCCC2)ccc1N1CCOCC1
