Task: Answer the MCQ question.
Question: Which drug exhibits a -20.699% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a) CC(=O)Cc1cc2cc([N+](=O)[O-])ccc2oc1=O
b) O=C(O)c1cc(S(=O)(=O)N2CCCC2)ccc1Br
c) O=C(Nc1ccccc1)Nc1ccc2c(c1)CCC2
d) CNc1n[nH]c(=S)s1
e) Cl.O=C(CN1C2=NCCN2c2ccccc21)c1ccco1
Answer: e. Cl.O=C(CN1C2=NCCN2c2ccccc21)c1ccco1
