Task: Answer the multiple choice question.
Question: Which compound exhibits a 7.468\% 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: CN1C(=O)C2C=CC1C1C(=O)N(c3ccccc3)C(=O)C21
b: CCOC(=O)C1(Cc2cccc(F)c2)CCN(Cc2ccc(COC)o2)CC1
c: O=C(N/N=C/c1ccc(Br)o1)c1cccnc1
d: CCOC(=O)c1cnc(-n2nc(C)cc2C)nc1NC1CCCC1
Answer: b. CCOC(=O)C1(Cc2cccc(F)c2)CCN(Cc2ccc(COC)o2)CC1
