Problem statement: Answer the MCQ question.
Question: Which drug has a 4.503\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) COC(=O)C1=C(C)Nc2c(c(=O)n(C)c(=O)n2C)C1c1ccc(C)cc1
(b) COc1ccccc1/C=C1\C(=O)NC(=S)N(c2ccccc2)C1=O
(c) O=[N+]([O-])/C=C1/CCCCCN1
(d) Cc1[nH]c2ccccc2c1/C=N/NC(=S)NC(C)C
(e) O=S1(=O)CCOC[C@H](CC2CCCCC2)N1Cc1ccccc1Br
Answer: c. O=[N+]([O-])/C=C1/CCCCCN1
