Task: Answer the MCQ question.
Question: Which drug exhibits a 10.805\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: COc1ccc(-c2ccc(=O)n(Cc3c(F)cccc3Cl)n2)cc1
b: COc1ccc(N(Cc2cc3ccccc3[nH]c2=O)C(=O)C2CCCO2)cc1
c: COc1ccc(NC(C)=O)cc1C
d: COc1ccc(-c2cc(C(F)(F)F)nc(SCC(=O)Nc3ccc4c(c3)OCO4)n2)cc1
e: Cn1c(=O)c2cc(S(=O)(=O)NC(C(=O)NCc3cccnc3)c3ccccc3)ccc2n(C)c1=O
Answer: a. COc1ccc(-c2ccc(=O)n(Cc3c(F)cccc3Cl)n2)cc1
