Task: Answer the multiple choice question.
Question: Which drug exhibits a 5.113\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a O=C(Nc1ccncc1)c1ccc(N2CCCC2=O)cc1
b CCN(C(=O)CN1CCN(c2cccc(Cl)c2)CC1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
c O=C(NCCC1=CCCCC1)C1CCN(S(=O)(=O)c2cccc3cccnc23)CC1
d C=CCC1(C)C(=O)N(c2ccccc2)c2ccccc21
e O=C(Cn1c(C(=O)OCCO)cc2ccccc21)c1ccccc1
Answer: b. CCN(C(=O)CN1CCN(c2cccc(Cl)c2)CC1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
