The correct answer is option 'A', Suez Canal.

Explanation:
The Suez Canal is an artificial sea-level waterway in Egypt, connecting the Mediterranean Sea to the Red Sea through the Isthmus of Suez. It was opened in November 1869, and since then it has shortened the distance between India and Europe. The canal has reduced the distance between the ports of Mumbai and London by approximately 7,000 kilometers. Before the Suez Canal, ships had to travel around the southern tip of Africa to reach Europe from India, which took a longer time and was more dangerous due to adverse weather conditions.

Advantages of the Suez Canal:

1. Reduced travel time: The Suez Canal has reduced the travel time between India and Europe by providing a direct route through the Isthmus of Suez.

2. Reduced transportation cost: The shorter distance and reduced travel time have reduced transportation costs significantly.

3. Boosted trade: The canal has boosted trade between India and Europe, as it has made the transportation of goods faster and cheaper.

4. Improved global connectivity: The Suez Canal has improved global connectivity by providing a direct route between the Mediterranean Sea and the Red Sea.

In conclusion, the Suez Canal has shortened the distance between India and Europe, reducing travel time, transportation costs, and boosting trade between the two regions.
