Task: Answer the multiple choice question.
Query: Which drug has a 24.195\% 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 other words.
Options:
a) Cc1cccc(NC(=O)/C(C#N)=C/c2ccc[nH]2)c1C
b) COc1ccc(OCCCC(=O)Oc2ccc(OC)cc2)cc1
c) O=C(NCc1ccco1)c1ccc(Cl)c(S(=O)(=O)Nc2ccccc2)c1
d) O=C(Cc1ccc(Cl)cc1)Nc1ccc(C(=O)N2CCOCC2)cc1
Answer: a. Cc1cccc(NC(=O)/C(C#N)=C/c2ccc[nH]2)c1C
