Class B
An ATC clearance is required before you enter.
The words matter: being told “stand by” is not a clearance, and neither is being given a squawk. You need “cleared into the Class Bravo”. Mode C is required within 30 nm of the primary airport — the veil — whether or not you enter the Bravo itself, and the VFR weather minimum is 3 statute miles and clear of clouds, because ATC is separating everyone inside.
