Task: Answer the multiple choice question.
Question: Which drug has a 20.396\% 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 CCOC(=O)C1CCN(S(=O)(=O)c2cccc(C(=O)Nc3ccccc3)c2)CC1
b COc1cccc(N/C=C/C(=O)c2ccc(C)cc2)c1
c O=C(NC1CCCCCCC1)c1c(O)c2ccccc2[nH]c1=O
d Cc1[nH]c2ccc(-c3n[nH]c(=S)n3Cc3ccccc3)cc2c1C
Answer: c. O=C(NC1CCCCCCC1)c1c(O)c2ccccc2[nH]c1=O
