Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a 13.243\% human ether-à-go-go related gene (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) Cc1[nH]c2ccccc2c1/C=N/NC(=O)c1cccc([N+](=O)[O-])c1
b) O=C(NCc1cccnc1)c1ccc(COc2ccc3c(c2)CCC3)o1
c) CC(/C=N/NC(=O)c1cc(-c2ccncc2)nc2ccccc12)=C\c1ccco1
d) COc1ccccc1NC(=O)/C=C/C(N)=O
Answer: d. COc1ccccc1NC(=O)/C=C/C(N)=O
