How did tax exemptions for land reclamation programs affect the central government of japan?

it was strengthened and developed a large army.
it was weakened and could not provide military protection.
it was forced to launch a series of religious wars.
it was divided, resulting in two emperors.

The correct answer is It was weakened and could not provide military protection. This meant that if anyone wanted to take these lands for themself if they were rich, they could do it with ease, because the government could not provide soldiers who would take it back or defend it from those who would take it for themselves.
