    Consider the following statements:In the case of gears of involute pr...
    Explanation:

    1. Increase in the pressure angle:
    When the center-to-center distance between the mounting shafts increases, the pressure angle of the gears also increases. This is because the pressure angle is influenced by the geometrical parameters of the gears, including the center-to-center distance.

    2. Will not affect the law of gearing:
    The law of gearing states that the angular velocity ratio of a pair of gears in mesh remains constant throughout the meshing process. The center-to-center distance between the mounting shafts does not affect this fundamental principle of gearing.

    3. Shortens the path of contact:
    Increasing the center-to-center distance between the mounting shafts shortens the path of contact between the gear teeth. This can have implications for the distribution of load and stress along the teeth during operation.

    4. Increases the contact ratio:
    The contact ratio is a measure of the average number of teeth in contact between a pair of gears during their meshing process. Increasing the center-to-center distance between the mounting shafts can increase the contact ratio, which can lead to smoother operation and reduced wear on the gear teeth.
    Therefore, statements 1, 2, and 3 are correct. Hence, the correct answer is option B.
