Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 14.123\% 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 additional words.
Options:
a. COc1cccc(C(=O)NC2CCN(C(=O)N3CCCCC3)CC2)c1
b. Cn1c(=O)[nH]c(=O)c2c1nc(Br)n2Cc1cccc(Br)c1
c. CCOCCCNC(=O)C(NC(=O)c1ccc(NC(C)=O)cc1)c1ccc(OC)cc1
d. C=CCSC1=N/C(=C/c2ccsc2)C(=O)N1c1ccccc1
e. O=C(Cc1cc(=O)[nH][nH]1)N/N=C/c1cccc(Cl)c1Cl
Answer: b. Cn1c(=O)[nH]c(=O)c2c1nc(Br)n2Cc1cccc(Br)c1
