The correct answer is Option 3, "1,3& 4."

Statement (3) is incorrect because humans do not exhibit a strict diphyodont dentition. Instead, humans have three sets of teeth: deciduous (baby) teeth, permanent teeth, and third molars (wisdom teeth) that may or may not develop.

All the other statements (a, b, and d) are correct:

(1) The alimentary canal does indeed start with the buccal cavity, which is another term for the mouth.

(2) Teeth are indeed embedded in sockets of the mandible bone.

(4) The esophagus and the trachea both open into the pharynx, which serves as a common passage for food and air.

So, the incorrect statement is 3, making Option 3 the correct answer.
