Answer:

U={a,b,c,d,e,f,g,h}

A={a,b,c,d}

now,

AUB= {a,b,c,d,e,f,g,h} U {a,b,c,d}

= {a,b,c,d,e,

ok,this question is wrong btw ,I think I stead of U(universal set) it is B
There is a confusion with the font used here as U has two different meanings and needs two different symbols.

The universal set is {a, b, c, d, e, f, g, h}

AUB is the union of set A and set B, that is all the elements in either A or B
= {a, b, c, d, e, h}
f and g are not in the union as they are not part of either A or B
