Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.928\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CSCCC(NC(=O)c1ccco1)C(=O)N1CC=C(c2ccccc2)CC1
b: CC1CN(c2ccc(NC(=S)NNCCC#N)cc2)CC(C)O1
c: COc1ccc(N(C(=O)Nc2ccc(Cl)cc2)C2=NCCC2)cc1
d: COc1ccc(-c2cc(C(F)(F)F)nc(SCCC(=O)N3CCOCC3)n2)cc1
Answer: a. CSCCC(NC(=O)c1ccco1)C(=O)N1CC=C(c2ccccc2)CC1
