Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -4.274\% 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 Cc1cc(NC(=O)CCN2C(=O)C3C4C=CC(C4)C3C2=O)ccc1Br
b C=CCNC(=S)NCC=C
c COc1ccc(Br)cc1S(=O)(=O)n1c([N+](=O)[O-])cnc1C
d Cc1cc2nc(SCCN3CCCC3)[nH]c2cc1C
Answer: a. Cc1cc(NC(=O)CCN2C(=O)C3C4C=CC(C4)C3C2=O)ccc1Br
