Task: Answer the MCQ question.
Question: Which drug has a 6.850\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) O=C1/C(=C\c2ccccc2)CCc2c1[nH]c1ccccc21
b) Cc1c(NC(=O)c2cc(-c3ccccc3)on2)c(=O)n(-c2ccccc2)n1C
c) CC(NC(=O)/C(C#N)=C/c1cccs1)c1ccccc1
d) COc1ccc2cc3cc(C(=O)NC4CC4)sc3nc2c1
Answer: a. O=C1/C(=C\c2ccccc2)CCc2c1[nH]c1ccccc21
