Explanation:

- Option 1: The Act aims to regulate and control the increase of rent for certain buildings and rented land within urban areas. It ensures that rent hikes are fair and manageable for tenants.

- Option 2: It also seeks to prevent the eviction of tenants without just cause, offering them protection and stability.

- Option 3: This option includes both aspects mentioned in Options 1 and 2. The Act controls both rent increases and tenant evictions in urban areas.

- Option 4: This option suggests that the Act does not concern itself with either rent control or eviction prevention, which is incorrect.
