Solution

The correct option is A True
The arrangement of metals in decreasing order of their reactivities is called is reactivity series.
$K N a C a A l Z n F e S n P b H C u H g A g$
$⟶$
Decreasing order of reactivity.
More active (reactive) metals than a particular metal can displace that metal.
Just like that, more reactive metals than $H$ , can displace $H$ from the acids(they have $H^{+}$ ) and $H^{+}$ is reduced to $H_{2}$ .
$N a + H_{2} S O_{4} ⟶ N a_{2} S O_{4} + H_{2}$
$C u + H_{2} S O_{4} ⟶ N o r e a c t i o n$
