Task: Answer the MCQ question.
Question: Which drug exhibits a -0.619\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] O/N=C1/CCCCc2sccc21
[b] O=C(O)c1ccccc1/C=N/NC(=S)NCc1ccccc1
[c] COc1ccc(C=O)cc1CN1CCCN(Cc2ccc(Cl)cc2)S1(=O)=O
[d] CC1=C(OC(=O)C(C)(C)C)C(C)(C)C(c2ccccc2)OC1=O
Answer: d. CC1=C(OC(=O)C(C)(C)C)C(C)(C)C(c2ccccc2)OC1=O
