A. Tarbela Dam

Here's why:

Tarbela Dam is the world's largest earth-filled dam and the second-largest by structural volume. It's located on the Indus River in Khyber Pakhtunkhwa province.

Mangla Dam is another major dam in Pakistan, but it's smaller than Tarbela Dam.

Warsak Dam is a much smaller dam compared to Tarbela and Mangla.

A. Angel Falls

Here's why the other options are not the answer:

Great Fall: This term is not specific and doesn't refer to a single waterfall.

Victoria Falls: While Victoria Falls is one of the most famous waterfalls in the world, it's not the highest.

Boyoma Falls: Boyoma Falls is also not the highest waterfall.

Angel Falls holds the title of the world's highest waterfall with a plunge of over 979 meters (3,212 feet).
