- Sequence: Starts from head (eye), moves to ear, then goes internally downwards.

- Option 2: 5 - 3 - 1 - 4 - 2

- Pinna (Ear) ? Cornea (Eye) ? Heart ? Kidney ? Pelvis

- Sequence: Starts from ear, moves up to eye, then goes internally downwards.

- Option 3: 3 - 5 - 4 - 1 - 2

- Cornea (Eye) ? Pinna (Ear) ? Kidney ? Heart ? Pelvis

- Sequence: Does not correctly follow a logical downward or functional flow.

- Option 4: 2 - 1 - 4 - 3 - 5

- Pelvis ? Heart ? Kidney ? Cornea (Eye) ? Pinna (Ear)
