All of the following are true about William Jennings Bryan except:

A he was a presidential candidate for the populist party

B he won the Presidential election of 1896

See he was a skillful speaker

D he was a well-known and popular with many Americans

B he won the Presidential election of 1896

Explanation:

William Jennings Bryan was an American politician who grew up in Nebraska. Although he ran as a candidate for the Presidential position, he never won the Presidential election of 1896. He even ran again twice, in 1900 and 1908, respectively.

The 1896 Presidential election was intensely fought. However, William Mckinley (a Republican) won as the President.

This makes "choice B" as incorrect.

So, this explains the answer.
