Problem statement: Answer the MCQ question.
Question: Which drug has a 14.101\% 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 CC(C)[C@H](NC(=O)C1CCCC1)c1nc2ccccc2[nH]1
b CCOc1ccc(NS(=O)(=O)c2ccc3[nH]c(=O)[nH]c3c2)cc1
c CCCCN1C(N)=NC[C@@H]1C(C)O
d CCOC(=O)c1[nH]c2ccc(Br)cc2c1NC(=O)CCN1CCOCC1
e CCN(CC)Cc1cc(C(=O)O)c(C)o1
Answer: c. CCCCN1C(N)=NC[C@@H]1C(C)O
