(B) Momentum $(p)$ is defined as the product of mass $(m)$ and velocity $(v)$,given by the formula: $p = m \times v$.
For body $A$:
Mass $(m_A)$ = $1 \ kg$
Speed $(v_A)$ = $10 \ m s^{-1}$
Momentum $(p_A)$ = $1 \ kg \times 10 \ m s^{-1} = 10 \ kg \ m s^{-1}$.
For body $B$:
Mass $(m_B)$ = $2 \ kg$
Speed $(v_B)$ = $9 \ m s^{-1}$
Momentum $(p_B)$ = $2 \ kg \times 9 \ m s^{-1} = 18 \ kg \ m s^{-1}$.
Comparing the two values,$18 \ kg \ m s^{-1} > 10 \ kg \ m s^{-1}$.
Therefore,body $B$ has more momentum.
