Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 18.868\% 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, or c without using any additional words.
Options:
[a] Cc1cc(NC(=O)CSc2n[nH]c(=O)[nH]c2=O)ccc1Br
[b] O=C(COC(=O)/C=C/c1ccccc1Cl)NC1CCCCCC1
[c] O=C(OCc1ccccc1Cl)c1cc([N+](=O)[O-])ccc1N1CCOCC1
Answer: a. Cc1cc(NC(=O)CSc2n[nH]c(=O)[nH]c2=O)ccc1Br
