Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.458\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a OCC1CCCN(Cc2cn(Cc3ccccc3)nc2-c2cc3ccccc3o2)C1
b Cc1ccc2c(c1)C1(SCCS1)C(=O)N2
c CC(C)[C@@H](N)C(=O)N/N=C/c1ccc2nccnc2c1.Cl
d Cc1c(NC(=O)C(C)Sc2nnc(-c3ccccc3)o2)c(=O)n(-c2ccccc2)n1C
Answer: b. Cc1ccc2c(c1)C1(SCCS1)C(=O)N2
