Sugar content in sugarcane on cane basis is about __________ percent by weight.

Answer: Option C

Sugarcane is a primary raw material used in the production of sugar.

The sugar content in sugarcane is typically expressed as a percentage of the total weight of the cane.

On average, the sucrose (sugar) content in sugarcane ranges from 15% to 20% by weight.

This percentage can vary based on factors such as variety, maturity, and growing conditions of the sugarcane.

Option A (1 to 5%) and Option B (5 to 10%) are too low and do not reflect typical commercial values.

Option D (20 to 30%) is too high and uncommon under normal agricultural practices.

Therefore, the correct and most accurate range is Option C: 15 to 20.
