Best answer
Correct option is (a) Chebyshev

Easiest explanation: Chebyshev technique is used to obtain array with any desired side lobe level. In Schelkunoff method, pattern is produced with null in specified directions. Woodward method is suited for beam shaping. Binomial array is used when no side lobes are desired.
