Task: Answer the MCQ question.
Query: Which drug exhibits a 13.005\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a O=C(O)CCCC(=O)Nc1ccc(C(=O)N2CCCCC2)cc1
b O=C(Nc1ccccc1F)c1ccc(-c2cccc([N+](=O)[O-])c2)o1
c CCCC(=O)Nc1ccc(C(=O)N/N=C/c2ccc[nH]2)cc1
d COc1ccccc1C(=O)Nc1nc2ccc(S(C)(=O)=O)cc2s1
e N#CC1=C(N)OC2=C(C(=O)CCC2)C1c1cccs1
Answer: a. O=C(O)CCCC(=O)Nc1ccc(C(=O)N2CCCCC2)cc1
