Final answer:
Adult cattle do not have any upper incisors, as they have a dental pad in the place where upper incisors would be in other animals. They use the dental pad in conjunction with the lower incisors to eat.
Step-by-step explanation:
Adult cattle actually do not have any upper incisors. Unlike humans who have eight incisors (four upper and four lower), cattle have a dental pad on their upper front, lacking upper incisors altogether. They use the dental pad along with the lower incisors to grasp and pluck grass. Therefore, the correct answer to how many upper incisors adult cattle have is:
None of the options a) 6 b) 8 c) 10 d) 12 are correct. They have 0 upper incisors.
