If the sum of the coefficient in the expansion of 1 - 3 x + 10 x 2 n is a and if the sum of the coefficients in the expansion of (1 + x 2) n is b, then : (1) a = 3b (2) a = b 3 (c) b = a 3 (4) None of these

If the sum of the coefficient in the expansion of ${(1 - 3 x + 10 x^{2})}^{n}$ is a and if the sum of the coefficients in the expansion of (1 + x ²) ⁿ is b, then :
(1) a = 3b (2) a = b ³ (c) b = a ³ (4) None of these
