Which of the following statements is true in reference to agriculture…

The discovery of grain suggests the existence of agriculture, but accurately reconstructing agricultural practices poses challenges. One question arises: Were seeds scattered on ploughed lands? Seals and terracotta sculptures portray the presence of bulls, leading archaeologists to infer their use in ploughing. Notably, terracotta models of ploughs have been unearthed at Cholistan and Banawali sites in Haryana. Furthermore, evidence of a ploughed field has been uncovered at Kalibangan in Rajasthan, dating back to the Early Harappan period. The field displayed two sets of furrows intersecting at right angles, indicating the simultaneous cultivation of two distinct crops.
