Task: Answer the multiple-choice question.
Query: Which drug exhibits a 13.738\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) NS(=O)(=O)c1ccc(NC(=O)CSC2=NC(=O)C(c3ccccc3)C(=O)N2)cc1
(b) CCOc1cc(/C=N/NC(=O)c2ccc(=O)n(C)c2)ccc1O
(c) Cc1ccc(C(=O)NC(C)c2ccc(-n3ccnc3)cc2)c(C)c1
(d) CNC(=O)/C(C#N)=C/c1c(N2CCN(C)CC2)nc2c(C)cccn2c1=O
Answer: d. CNC(=O)/C(C#N)=C/c1c(N2CCN(C)CC2)nc2c(C)cccn2c1=O
