Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 6.811\% 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, d, or e without using any additional words.
Options:
a Cc1ccc(C(=O)N(CCc2ccccc2)Cc2ccccc2)cc1S(=O)(=O)N1CCCCC1
b COc1ccc(-c2nn(-c3ccccc3)cc2/C=N/NC(=O)c2ccc(Br)o2)cc1
c CCc1c(C)[nH]c2nc3ccccc3n2c1=O
d Cc1cc(NC(=O)CN2CCC(C)CC2)no1.O=C(O)C(=O)O
e C=CCN1C(=O)[C@@H]2Cc3c([nH]c4ccccc34)C(c3cc(OC)c(OC)c(OC)c3)N2C1=S
Answer: c. CCc1c(C)[nH]c2nc3ccccc3n2c1=O
