Task: Answer the MCQ question.
Question: Which drug has a -11.561\% 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=C(CSc1ccc([N+](=O)[O-])cn1)Nc1ccc(N2CCOCC2)cc1
b) O=C(NCCCN1CCOCC1)/C(=C/c1cccnc1)NC(=O)c1ccccc1
c) COC(=O)C(Cc1c[nH]c2ccccc12)NC(=O)c1ccccc1Br
d) O=S(=O)(NCCc1cn2ccccc2n1)c1ccc(-c2ccccc2)cc1
Answer: d. O=S(=O)(NCCc1cn2ccccc2n1)c1ccc(-c2ccccc2)cc1
