The assertion states that the primary source of gold is alluvial deposits found in riverbeds. This statement is true.

The reasoning provided explains why gold is commonly found in riverbeds. Gold is indeed heavier than many other sediments and minerals found in rivers. Due to its higher density, gold tends to settle at the bottom of riverbeds through natural processes. Over time, the movement of water and erosion can concentrate gold particles, creating alluvial deposits in riverbeds. These deposits can be mined for gold.

Alluvial gold deposits have been historically significant sources of gold, and they continue to be important in present-day gold mining.

Therefore, both the assertion and reasoning are correct, and the reasoning provides a valid explanation for the assertion. Hence, option 1) is the correct option.
