Task: Answer the multiple choice question.
Question: Which drug exhibits a 18.148\% 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.) CCCCC(=O)N/N=C/c1c(O)n(-c2ccccc2)c(=O)[nH]c1=O
b.) O=C1/C(=C/c2cccs2)CCC1C1CCCC1
c.) N#C/C(=C/c1ccc(CNS(=O)(=O)c2ccccc2)o1)C(N)=O
d.) Cc1cnc(C(=O)OCC(=O)NC2CCCCCCC2)cn1
Answer: a. CCCCC(=O)N/N=C/c1c(O)n(-c2ccccc2)c(=O)[nH]c1=O
