Answer and explanation

Correct answer: {a,b,c,d,e,g,i,j}

The union A∪B contains every distinct element that belongs to A or B. Combining the two sets gives a, b, c, d, e, g, i, and j. The repeated elements c and g are written only once because sets do not repeat members. Hence A∪B={a,b,c,d,e,g,i,j}, option B.
