Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 4.857\% 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.) CC(C)CC(NC(N)=O)C(=O)OCC(=O)Nc1ccc(SC(F)F)cc1
b.) O=C(NC1CCCC1)C(c1c[nH]c2ccccc12)N(C(=O)Cn1nnc(-c2ccc(Cl)cc2)n1)c1ccccc1
c.) N#C/C(=C\c1ccc(Oc2ccc([N+](=O)[O-])cn2)cc1)C(=O)Nc1ccc(F)cc1
d.) Cc1ccc(C)n1-c1ccc(-n2cnnn2)cc1
Answer: c. N#C/C(=C\c1ccc(Oc2ccc([N+](=O)[O-])cn2)cc1)C(=O)Nc1ccc(F)cc1
