Answer:
c. tariffs subsidies
Explanation: This support is to encourage agriculture whilst reducing taxes and reducing import .
Importing have so much cost that are accumulated during the whole process which may affect farmers and their farming businesses.
Tariff subsidies then help the farmers and allow them to have less cost to their business whilst boosting the economy of the country through their farming businesses at a reasonable cost.
Since farming plays a huge role in the economy of the country it therefore benefits the government too.
