Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -1.345\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) O=C(N/N=C/C(Cl)=C/c1ccccc1)c1ccco1
(b) O=C(NCc1ccc(Cl)s1)C1CCC(=O)N(CCc2ccccn2)C1
(c) CC(C)OP(=O)(OC(C)C)C(NC(=O)c1cccc([N+](=O)[O-])c1)C(N)=O
(d) Cc1cc(NC(=O)c2ccc3[nH]c(C)c(C)c3c2)ccn1
(e) CC(=O)N(/N=C1/C(=O)Nc2ccccc21)c1ccccc1
Answer: a. O=C(N/N=C/C(Cl)=C/c1ccccc1)c1ccco1
