My dear let us begin from

My dear let us begin from scratch.

why do you have below settings on switch A on port 37

 switchport trunk allowed vlan 1,5,10,25,100
 switchport mode access

let us do simple things first.  ( make port setting of switch A prot 37 and switch B port 48 as default ).

and then simply trunk and check.

hope this helps.
