`Mg(OH)_2 + Al(OH)_3` Mixture is better antacid than `NaHCO_3` because

A

`NaHCO_3` Solubilty in water is less than `Mg(OH)_3` & `Al(OH)_3`

B

`Al(OH)_3 and Mg(OH)_2` are insoluble in water, these donot raise `P^(H)` beyond 7

C

Less acid will be produced due to excessive `HCO_3^(-)`

D

`NaHCO_3` is stomach irritant
