Task: Answer the multiple-choice question.
Query: Which drug has a 21.999\% 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 additional words.
Options:
a. O=C(C1CCCC1)N1CCN=C1SCc1cccc([N+](=O)[O-])c1
b. O=C(O)C1CCCN1S(=O)(=O)c1ccc(Br)s1.O=C(O)[C@@H]1CCCN1
c. Cc1cccc(NC(=S)NC(=O)Cc2ccccc2)c1C
d. N#CC(=C=[N-])/C=C(\C(=O)c1ccccc1)[n+]1ccccc1
Answer: c. Cc1cccc(NC(=S)NC(=O)Cc2ccccc2)c1C
