Task: Answer the MCQ question.
Question: Which drug has a -5.307\% 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 other words.
Options:
(a) CCS(=O)(=O)N1CCc2nc(-c3ccccc3)sc2C1
(b) NS(=O)(=O)c1ccc(N/N=C/c2ccc[nH]2)c([N+](=O)[O-])c1
(c) O=C(CNC(=O)c1ccccc1)N/N=C/c1cn[nH]c1-c1ccccc1
(d) O=C(CSc1ccc(-c2ccccc2)nn1)NCc1ccco1
(e) CCn1nc([N+](=O)[O-])c2c(-c3nc4ccccc4o3)c(N)n(CCCOC)c2c1=O
Answer: a. CCS(=O)(=O)N1CCc2nc(-c3ccccc3)sc2C1
