The electropositive character of elements in group 13 increases as you move down the group. This is due to the decreasing ionization energy and increasing atomic size, which make it easier for the elements to lose electrons. The correct order is:

Electropositive Character Order

Increased Electropositivity: As you go from boron (B) to thallium (Tl), the elements become more electropositive.
Correct Sequence: The order is: Al > Ga > In > Tl.

Therefore, the correct answer is option A: B > Al > Ga > In > Tl.
