Task: Answer the multiple-choice question.
Query: Which drug exhibits a 15.493\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. CCc1[nH]nc2c1C1(C(=O)N(Cc3ccccc3)c3ccccc31)C(C#N)=C(N)O2
b. COc1cccc(Oc2coc3c(CN4CCOCC4)c(O)ccc3c2=O)c1
c. O=S(=O)(/N=C(/Nc1ccccc1)c1ccccc1)c1cccs1
d. CCN(CC)S(=O)(=O)c1ccc(N2CCOCC2)c(NC(=O)c2ccc(OC)c([N+](=O)[O-])c2)c1
Answer: a. CCc1[nH]nc2c1C1(C(=O)N(Cc3ccccc3)c3ccccc31)C(C#N)=C(N)O2
