Which of the following has higher enol content?
The two main factors affecting the stability of the enol forms of (A) and (B) are 


Hydrogen bonding
Aromaticity


In the enol form of both compounds, hydrogen bonding is present:



But the resonance structure of enol form of (B) is aromatic. It contains $6$ $\pi$-electrons:



The enol form of (A) lacks this stability. Hence, the enol content of (B) is more than that of (A)
