Task: Answer the MCQ question.
Query: Which drug exhibits a -5.452\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] O=C(NC1CCCc2ccccc21)c1ccc(=O)[nH]c1
[b] CSCC(O)Cn1[nH]c(=O)c2cc(Cl)c(Cl)cc2c1=O
[c] COc1ccc(C(C(=O)NC2CCCC2)N(C(=O)c2ccco2)c2cc3c(cc2C(C)=O)OCO3)cc1
[d] C=CCN1C(=O)N/C(=C/c2ccc(N3CCOCC3)o2)C1=O
[e] c1ccc(Nc2nc(-c3cccnc3)cs2)nc1
Answer: a. O=C(NC1CCCc2ccccc21)c1ccc(=O)[nH]c1
