The 2010 Eyjafjallajokull eruption caused the largest air travel disruption since World War II, affecting over 10 million passengers and costing airlines billions. The eruption ash cloud grounded flights across Europe for nearly a week. This was the most significant aviation disruption since WWII.

The Eyjafjallajokull eruption in April 2010 had a Volcanic Explosivity Index (VEI) of 4, classifying it as a cataclysmic eruption. VEI ranges from 0 to 8, with 4 representing significant explosive activity. This was sufficient to inject ash into the jet stream and disrupt air traffic across Europe.

Iceland has approximately 130 volcanic mountains, of which about 18 have erupted since human settlement began around 874 AD. Iceland is one of the most volcanically active places on Earth due to its location on the Mid-Atlantic Ridge. The numbers reflect both the total volcanic systems and historically active ones.

The 2010 Eyjafjallajökull eruption was exceptionally disruptive due to a perfect storm of geographical and geological factors. The volcano's position directly under the jet stream (A) allowed ash to be carried across Europe quickly. The eruption occurred beneath 200m of glacial ice (B), causing rapid magma cooling that increased explosive power and created highly abrasive, glass-rich ash particles (C). This combination injected fine ash directly into the jet stream (D), which then dispersed across major air traffic routes, forcing widespread flight cancellations.

During the 2010 eruptions, European air traffic was grounded for nearly a week, forcing travelers to seek alternative transportation methods. Railways (B) and road transport services (C) experienced significantly increased demand and revenue as stranded passengers needed to reach their destinations by land. Additionally, volcano tourism (D) saw a surge in interest as people traveled to witness the eruption spectacle, creating unexpected economic opportunities amid the disruption.

Rabindranath Tagore won the Nobel Prize in Literature in 1913, not 1931. He was the first non-European to win this prize, awarded for his collection of poems 'Gitanjali'. The statement is false, so Option B is correct.

Shashanka (c. 600-625 CE) is widely regarded as the first independent king of Bengal. He established his kingdom in the early 7th century and is known from contemporary accounts and the Harsha inscription. The Sena kings (Lakkhan Sen and Ballal Sen) ruled much later (11th-12th century), while Gopal is associated with the Pala dynasty.

Gopal was the founder of the Pala Dynasty (not Pal) in Bengal, ruling from approximately 750-750 AD. He established the dynasty after being elected by prominent chieftains following the absence of central authority in the region. The Pala Dynasty ruled Bengal and Bihar for nearly four centuries.

Lakkhan Sen (also known as Lakshmana Sen) was the last ruler of the Sena Dynasty in Bengal, ruling from approximately 1179-1206 AD. During his reign, the dynasty faced invasions from the Delhi Sultanate, and he was eventually defeated by Bakhtiyar Khilji in 1206, marking the end of Sena rule in Bengal.
