Answer:
b. passing secret government documents on to the Soviets
Step-by-step explanation:
Alger Hiss was an important government official in the United States of America.
In the year 1948, Alger Hiss appeared before the House Un-American Activities Committee (HUAC) after a series of accusations had been leveled against him saying he was a spy to the Soviet Union as well as a communist.
On the 3rd of August, Alger Hiss was accused of been a communist spy to the Soviet Union by a man who served as a witness to the case called Whittaker Chambers( a former member of the communist party) an Editor of a magazine called the Time.
Alger Hiss claimed not to have known who Mr Whittaker Chambers was but Mr Whittaker showed a series of top secret American documents that Alger Hiss had given to him as evidence to the House Un-American Activities Committee (HUAC).
Alger Hiss later admitted to knowing who Whittaker Chambers was but he claimed Mr Whittaker Chambers was using another name then.
His trial continued for a very long time and due to the fact that the statues of limitations had been exhausted , he was convicted of perjury he was charged with two counts of perjury for lying about passing top secret government documents to Mr Whittaker Chambers and for denying that he had seen him since 1937.
In the year 1949, the first trial for perjury before a jury ended in a deadlock. The second trial ended in January 1950 where he was declared guilty on both counts.
