Task: Answer the MCQ question.
Question: Which drug exhibits a 12.970\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) CSC1=N/C(=C\c2ccccc2C)C(=O)S1
b) N#CC(C#N)=c1ccc2c(c1)NC1(CCCCC1)N=2
c) Cn1c(=O)[nH]c(=O)c2c1nc(CN1CCOCC1)n2CCCO
d) O=C(Nc1nnc(CC2=CCCCC2)s1)c1cccs1
Answer: b. N#CC(C#N)=c1ccc2c(c1)NC1(CCCCC1)N=2
