Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.566% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a Cn1c(=O)c(=O)n(C)c2cc(S(=O)(=O)N3CC(=O)N(CCc4ccccc4)C(=O)C3)ccc21
b Cc1cc(N2CCN(S(=O)(=O)c3ccc(Br)cc3)CC2)n2ncnc2n1
c Nc1c(S(=O)(=O)c2cccs2)c2nc3ccccc3nc2n1/N=C/c1cccc(O)c1
d C=CCNC(=S)NNC(=O)c1cc(O)ccc1O
Answer: c. Nc1c(S(=O)(=O)c2cccs2)c2nc3ccccc3nc2n1/N=C/c1cccc(O)c1
