Task: Answer the multiple choice question.
Query: Which drug has a 3.235\% 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 additional words.
Options:
(a) CCN1C(=O)C2(C(C#N)=C(N)Oc3n[nH]c(COC)c32)c2ccccc21
(b) O=C(CN1CCC(NC(=O)Nc2ccc(F)cc2)CC1)Nc1ccccc1[N+](=O)[O-]
(c) O=S(=O)(NCCCN1CCOCC1)c1ccc(Cl)s1
(d) N=c1nc(SCCC(=O)O)ss1
Answer: a. CCN1C(=O)C2(C(C#N)=C(N)Oc3n[nH]c(COC)c32)c2ccccc21
