Task: Answer the multiple choice question.
Query: Which drug has a 4.780% 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. CCOC(=O)/C(C#N)=C(/C)c1ccc(OC)cc1
b. O=C(Nc1ccccc1)N(CCCN1CCOCC1)Cc1cc2cc3c(cc2[nH]c1=O)OCCO3
c. O=C(c1cc(S(=O)(=O)N2CCOCC2)ccc1F)N1CCCc2ccccc21
d. Nc1nc(Cl)cc(NCCc2ccc(O)cc2)n1
Answer: a. CCOC(=O)/C(C#N)=C(/C)c1ccc(OC)cc1
