Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.376% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. O=C(O)COc1ccccc1O
b. Cc1c(O)c2c3c(cccc3c1O)C(=O)N(c1ccccc1)C2=O
c. CS(=O)(=O)NCCCc1ccccc1
d. CCNS(=O)(=O)c1ccc(NC(=O)c2cncc(Br)c2)cc1
Answer: a. O=C(O)COc1ccccc1O
