Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -7.769\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CCOC(=O)C1CCN(C(=O)/C=C/c2ccccc2OC)CC1
(b) O=C(Cn1[nH]c(=O)c2ccccc2c1=O)NCc1cccnc1
(c) CCCCCCCCCCCC1=C(O)C(=O)C=C(O)C1=O
(d) O=C(C1CCN(S(=O)(=O)c2ccc3ccccc3c2)CC1)N1CCN(c2ncccn2)CC1
Answer: a. CCOC(=O)C1CCN(C(=O)/C=C/c2ccccc2OC)CC1
