Copper is less reactive than tin.

The correct option is A True

Activity series: Activity series is the arrangement of metal in a tabular form in the decreasing order of their reactivity.

Activity series

$\mathrm{K}>\mathrm{Na}>\mathrm{Li}>\mathrm{Ba}>\mathrm{Sr}>\mathrm{Ca}>\mathrm{Mg}>\mathrm{Al}>\mathrm{Mn}>\mathrm{Zn}>\mathrm{Cr}>\mathrm{Fe}>\mathrm{Cd}>\mathrm{Co}>\mathrm{Ni}>\mathrm{Sn}>\mathrm{Pb}>\mathrm{H}>\mathrm{Sb}>\mathrm{Bi}>\mathrm{Cu}>\mathrm{Hg}>\mathrm{Ag}>\mathrm{Au}>\mathrm{Pt}$

• The metal present at a higher position can displace the element which is present below that element in the activity series.
• So from the reactivity series, we can see $\mathrm{Sn}$ (Tin) is more reactive than $\mathrm{Cu}$ (Copper).

Thus, the above statement is true.
