Answer:

Explained below

Step-by-step explanation:

Group 3A elements are made up of the metalloid - boron (B) and other metals such as Aluminum (Al), gallium (Ga), indium (In), & thallium (Tl).

Now, as we go down the group, the size of the central atom will increase thereby causing the lone pair to become delocalized over a larger volume space. Thus, it's not readily available for donation and thus basicity increases
