To determine which of the following issues did not contribute to the spread of the revolt of 1857, we need to analyze each option and identify any potential connections to the uprising.

a. Issue of cartridges: The issue of cartridges refers to the introduction of new rifle cartridges that were rumored to be greased with animal fat, which offended both Hindu and Muslim soldiers. This issue played a significant role in sparking the revolt, as it led to widespread discontent among the sepoys (Indian soldiers).

b. Conversion of Indians to Christianity: The conversion of Indians to Christianity was a contentious issue during the British colonial period. While it may have contributed to underlying tensions between the British and Indian population, it is not directly linked to the specific events of the revolt of 1857.

c. Mixing of bone dust in flour: The mixing of bone dust in flour was a practice employed by some British traders, which was seen as disrespectful and offensive to the religious beliefs of Hindus and Muslims. This issue, similar to the cartridge issue, contributed to the growing discontent among the sepoys and played a role in the spread of the revolt.

d. Giving due right to the princely states: The princely states were semi-autonomous regions within British India, ruled by Indian princes. While the issue of giving due rights to the princely states may have been a point of contention between the British and the Indian population, it is not directly linked to the specific causes or spread of the revolt of 1857.

Based on the analysis above, the issue that did not directly contribute to the spread of the revolt of 1857 is b. Conversion of Indians to Christianity.
