{'compound microscope': [0, 0, 0, 2], 'objective lens': [0, 0, 0, 1], 'eyepiece': [0, 0, 2, 4], 'eye piece': [0, 0, 0, 2], 'light': [16, 4, 34, 62], 'passage': [1, 0, 5, 9], 'condenser': [0, 0, 0, 1], 'body tube': [0, 0, 0, 1], 'mirror': [0, 0, 0, 1]}

Option 1: Condenser - Objective lens - Eyepiece - Body tube

This option is incorrect. In a compound microscope, the light first passes through the condenser, then through the objective lens, and finally through the eyepiece. The body tube is the part that connects the objective lens and the eyepiece, so it should not come before the eyepiece in the sequence.

Option 2: Objective lens - Condenser - Body tube - Eyepiece

This option is not the correct sequence. The light first passes through the condenser before reaching the objective lens. So, the condenser should come before the objective lens in the sequence.

Option 3: Condenser - Objective lens - Body tube - Eyepiece

This is the correct sequence. The light passes through the condenser, then through the objective lens, and then through the body tube before reaching the eyepiece. This is the typical arrangement of the optical components in a compound microscope.

Option 4: Eyepiece - Objective lens - Body tube - Mirror

This option is incorrect. The mirror is used to reflect light into the microscope. The correct sequence would be mirror - condenser - objective lens - eyepiece. The order of the objective lens and ey
