Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
A furrow opener opens a narrow furrow in the soil for seed placement. The depth of sowing depends on how deep the opener penetrates into the soil.
Step 1: In a seed drill or planter, the furrow opener cuts the soil and makes space for seed placement.
Step 2: If the furrow opener is lowered, it penetrates deeper into the soil.
Step 3: If the furrow opener is raised, it makes a shallower furrow.
Step 4: Therefore, sowing depth is adjusted by raising or lowering the furrow opener.
Step 5: Hence, the correct answer is: \[ \boxed{\text{Raising or lowering the furrow opener}} \]
