The correct answer is false.
It is false that the experts were wrong in their estimation of the distance to Asia going west from Europe.
Christopher Columbus disagreed on how far the distance was from Europe to Asia if they were going west from Europe. So in the end, Columbus received the sponsorship of King Fernando de Aragon and Queen Isabella of Castille to explore a new route to the Indians. And that is how he arrived in the Americas -to the Caribbean Islands- on October 12, 1492.
