You need to put the word IN before 1492 in the second sentence ... It was 1492 when Christopher Columbus discovered America. It was in 1942 that Christopher Columbus discovered America .. otherwise if could sound like you are telling America that Christopher Columbus discovered 1492 !

Yes, but the first sentence is better and would be even better if you inserted "in" before "1492."

A is correct. If you wanted to use "that" like in B, the sentence would have to include the word "in" like this: "It was in 1492 that Christopher..."

In everyday English you might find both versions in use by native speakers of British English. Neither version is "correct" according to classical notions of grammar. Possibly the most common ways of expressing that idea would be: "In 1492 Columbus discovered America", or "Columbus discovered America in 1492".

WHEN. People can not be THAT

Your using " that" and "what" in both of those sentences.

Basically, but A is correct because referring to a year as "that" alone, rather than "that year is when" is wrong. If a year is cited, then "when" is the proper word.

The first is correct; the second is not. To make the second correct, you would add the word "in" before 1492. THEN they would mean the same thing.
