Task: Answer the MCQ question.
Query: Which drug exhibits a -1.700\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a O=C(NNC(=O)c1cc(Br)ccc1O)c1csc(N2CCOCC2)n1
b O=S(=O)(c1ccc(Br)s1)N1CCN(Cc2ccc3c(c2)OCO3)CC1
Answer: a. O=C(NNC(=O)c1cc(Br)ccc1O)c1csc(N2CCOCC2)n1
