    Explanation:
    Females in division A = 1,00,000
     
    Half of it = 1/2  × 1,00,000 = 50,000
    Females in division C = 40,000
    one-fourth of it = 1/4  × 40,000 = 10,000
    Females in division D = 1,10,000
    one-fourth of it = 1/5  × 1,10,000 = 22,000
    Total females on training = 82,000
    On a pie chart we should have,
     
    82,000 = 360°
     
    In division C has 10,000 on training,
     
    10,000 on pie chart =(  10,000 × 360°)/82,000
    = 43.9 = 44° (approximately)
     
    Hence, option C is correct.
