Option 3 : Both (1) and (2)

Kaiser window is a method that is used infinite impulse response filter design and spectral analysis.
This method reduces the sidelobe level by controlling and modifying the n^th order Bessel function & also controls the shape factor by adjustable parameter α which result maximizes the energy concentration in the main lobe.
Kaiser window separately controls the order of filter (M) and the transition width of the main lobe.

Methods of FIR filter design:

1.) The window method

Bartlett triangular window
Generalized cosine window
Kaiser window

2.) The Frequency Sampling Technique

3.) Optimal Filter Design Methods

Least squared error frequency domain design
Weighted Chebyshev approximation
Nonlinear equation solution for maximal ripple FIR filters
Polynomial interpolation solution for maximal ripple FIR filters
