Step 1: The impact of the Great Depression
The Great Depression that began in 1929 had severe effects on many sectors. The most significant impact was on the Agriculture Sector, as the prices of crops dropped drastically, leading to widespread hardship for farmers.
Step 2: Why the other options are incorrect
- (A) Transport: Although transport was affected, it was not the sector that suffered the most during the Great Depression.
- (C) Technology: Technology, especially in the industrial sector, faced slowdowns, but it was not the primary sector impacted.
- (D) None of the above: The agriculture sector was, in fact, the most impacted, making this option incorrect.
Thus, the correct answer is option (B) Agriculture Sector.
