Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 2.156% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CC(=O)c1cccc(NS(=O)(=O)c2ccc3c(c2)N(C(C)=O)CCO3)c1
b O=C(N/C(=C/c1cn(-c2ccccc2)nc1-c1ccccc1)C(=O)N1CCOCC1)c1ccc(Cl)cc1Cl
c CC(=O)c1ccc(NC(=O)c2ccc(-n3cncn3)c([N+](=O)[O-])c2)cc1
d Cc1nccc2c1[nH]c1ccccc12
e COC1CCN(C(=O)CC2C(=O)NCCN2CC2CCCCC2)CC1
Answer: d. Cc1nccc2c1[nH]c1ccccc12
