Answer 2

HCL IS A STRONG ACID WHEREAS ACETIC IS A WEAKER ACID. FIZZING OCCURS BECAUSE OF THE PRODUCTION OF THE HYDROGEN GAS OBTAINED DUE TO REACTION OF THE ACID ON THE MAGNESIUM RIBBON. SINCE HCL IS A VERY STRONG ACID THERE IS A LOT OF LIBERATION OF HYDROGEN GAS FROM TEST TUBE A. THEREFORE, MORE FIZZING TAKE PLACE IN TEST TUBE A.
