Task: Answer the multiple choice question.
Question: Which drug has a 18.774\% 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 NS(=O)(=O)c1ccc(NC(=S)NC2CCCC2)cc1
b Cc1cc(C)c2nc(/N=C(\N)NC(=O)c3ccccc3)nc(C)c2c1
c O=C(N/N=C/C1CCCCC1)c1cc(Cl)ccc1O
d COc1ccc(CN(C)C(=O)c2ccc(NC(=O)CC3SC(N4CCCC4)=NC3=O)cc2)c(OC)c1OC
Answer: d. COc1ccc(CN(C)C(=O)c2ccc(NC(=O)CC3SC(N4CCCC4)=NC3=O)cc2)c(OC)c1OC
