Metal which reacts vigorously with HCl to produce salt and hydrogen is :

The correct option is A Na

For a metal to react with an acid to form a salt and hydrogen gas, it has to be above hydrogen in the electrochemical series.
The electrochemical Series is a list of elements in order of their reactivity (high to low).
Sodium reacted most vigorously hence producing a lot of hydrogen gas.
$2Na+2HCl\to 2NaCl+H_2$
Zinc should also have produced hydrogen gas quickly, however not as quickly or vigorously as Sodium (Na), and reactivity will be lesser for tin (Sn) and lead (Pb) respectively.
