I think its A .. Menstrual blood loss cause
1. increase blood loss cause decrease iron , decrease ferritin and increase TIBC , hypochromic smear
2. Normal haptoglobin and LDL ... cause there is no hemolysis ...

Why not others ....
B .... Iron study should be normal
C. increase ferritin but cell cant get that coz low Fe , low TIBC ...cause not known ...
D & E ... In any hemolysis LDL should increase and haptoglobin should decrease .....
