Problem statement: Answer the multiple-choice question.
Query: Which drug has a 15.699\% 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 additional words.
Options:
a C=COCCCNc1ncnc2sc(-c3ccccc3)cc12
b COc1cc(C(=O)Nc2nccs2)cc(OC)c1OC
c O=C(Nc1nc(-c2cc3ccccc3o2)cs1)c1ccc(S(=O)(=O)N2CCCC2)cc1
d O=C(O)c1ccc(N=NN2CCCC2)cc1
Answer: a. C=COCCCNc1ncnc2sc(-c3ccccc3)cc12
