The
interface or undercutting in involute gears can be avoided by
Varying
the centre distance by changing pressure angle
Using
modified involute or composite system

All
options are correct
All
options are correct
If
contact portions of tooth profiles of meshing gears are not involute, then the
gears do not execute conjugate action that is why the output gear will not have
constant angular velocity. This is called interference.
Interference
can be avoided by :
1. Increasing slightly the center distance
between the meshing gears or by using profile shifted gears.
2.Using a pinion with longer than the
standard addendum and the mating gear with shorter than the standard addendum.
3.By increasing pressure angle.
4.By increasing the number of teeth on
gears.
Hence,
the correct option is (D).
