Task: Answer the multiple-choice question.
Query: Which drug has a 6.356\% 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 COC(=O)/C(C#N)=C/c1ccc(-c2ccc(S(N)(=O)=O)cc2)o1
b O=C(O)c1ccccc1Nc1c([N+](=O)[O-])cc([N+](=O)[O-])c2cccnc12
c CCCCCc1c(C)[nH]c2nc3ccccc3n2c1=O
d CCOC(=O)C1CCN(C(=O)CCn2c(=O)[nH]c3ccccc3c2=O)CC1
e CC(NC(=O)c1ccccc1NC(=O)c1ccncc1)c1ccccc1
Answer: c. CCCCCc1c(C)[nH]c2nc3ccccc3n2c1=O
