Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.044\% 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 N#C/C(=C\c1cc([N+](=O)[O-])ccc1Cl)C(N)=O
b CCSc1nnc(NC(=O)c2cnccn2)s1
c CCN(CC)CCNC(=O)COc1ccc(Cl)cc1Cl
d Cc1ccc(Cn2c(C(=O)O)cc3sccc32)cc1
Answer: a. N#C/C(=C\c1cc([N+](=O)[O-])ccc1Cl)C(N)=O
