Which of the following is responsible for conductivity in intrinsic se...

In an intrinsic semiconductor, the number of electrons is equal to the number of holes. Hence at room temperature, no free electron is available for conduction
If some energy is applied to the atoms of intrinsic semiconductor the covalent bonds will break and electrons will be free
Each electron will leave behind a hole and the process will continue, and charge flows through the intrinsic semiconductor

Therefore intrinsic semiconductor conductivity is due to breaking off the covalent bond. Hence option (4) is correct
