Task: Answer the multiple choice question.
Question: Which drug exhibits a 9.944\% 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. CNC(=O)COc1ccc(C=O)cc1OC
b. CCNC(=S)N/N=C/c1sccc1C
c. COc1cc(OC)nc(Oc2ccc(N)c(C)c2)n1
d. Cc1cc2nc(C)c(=O)n(C)c2cc1C
Answer: b. CCNC(=S)N/N=C/c1sccc1C
