How did measures such as the Treaty of Balta Liman affect growth within the Ottoman Empire in the 19th century?

They resulted in a freer and fairer judicial system, but this prevented governors from maintaining control of frontier provinces.
They created the legal conditions for industrialization, but this was undermined by a flood of low-cost products from Britain.
They allowed consumers of all classes to access British products, but raised the prices of local products.
They helped the central government raise revenue, but weakened its control over the merchant class.

The 1838 Treaty of Balta Limani, or the Anglo-Ottoman Treaty, is a formal trade agreement signed between the Sublime Porte of the Ottoman Empire and the United Kingdom. The trade policies imposed upon the Ottoman Empire, after the Treaty of Balta Limani, are considered to be some of the most liberal, open market, settlements that had ever been enacted during the time. The terms of the treaty stated that, the Ottoman Empire will abolish all monopolies, allow British merchants and their collaborators to have full access to all Ottoman markets and will be taxed equally to local merchants.[1] These agreements did not constitute an equal free trade arrangement, as The United Kingdom still employed protectionist policies on their agricultural markets.
