English serves as the lingua franca in many international business settings.
The lingua franca of India and Pakistan is Urdu/Hindi.
A lingua franca is a common language that is used for communication between people of different languages and cultures. Lingua Franca is not a country, nor it is it located in any specific countries.
The current lingua franca is English, but that may be set to change in the next few years.
The lingua franca for India and Pakistan is Hindi/Urdu--which are functionally the same language.
There is no official lingua franca or pidgin language in Yemen. Arabic is the official language and is spoken by the majority of the population. However, due to historical connections with other countries, some Yemenis may speak English or other languages as a second language.
The Lingua Franca status is a descriptive term, and not a fixed status. Lingua Francas cannot be preserved. They change with the times.
Currently, Europe's lingua franca is English. However, not so long ago, the lingua franca of Eastern Europe was Russian (and sometimes German, depending on the proximity of a country to Germany as opposed to Russia).

The first lingua franca was likely Akkadian, an ancient Semitic language used in the Mesopotamian region around 2500 BCE for trade, diplomacy, and communication between different cultures. It later evolved into Aramaic which became a major lingua franca in the Near East.
English is the predominant world lingua franca, as it is widely used in international business, diplomacy, science, and tourism. It is often spoken as a second language by people around the world.
