The correct options are
A To propagate teachings of the Guru.
B To promote brotherhood and harmony between Sikhs and non-Sikhs.
D To raise funds for charitable causes.
Guru Ram Das Ji started the Masand system to raise funds for the construction of wells, Gurudwaras, and places for the community. In the Masand system, every Sikh is compelled to donate one-tenth of his income as Dasvandh for charitable causes. The representatives chosen by the Guru for raising funds were called Masands. Masands also propagated Sikhism among non-Sikhs while collecting funds. This contributed to the spread of the Sikh religion.
