Final answer:
During de Iturbide's tenure, democratic institutions were not established, making option 'D) Establishing democratic institutions and promoting political participation' incorrect. The period saw economic reforms, expansion of public education, and abolition of certain taxes, but no lasting democratic governance.
Step-by-step explanation:
All of the accomplishments listed, except establishing democratic institutions and promoting political participation, can be attributed to the period involving Agustin de Iturbide and the various other figures connected to the administration of Spanish colonies.
Looking at the reforms and events of the period, we find various initiatives such as trying to stimulate trade and economic development (economic reforms), welcoming the help of the Catholic Church to abolish old taxes in Spanish America, and the liberal reforms that included the expansion of public education.
