The correct answer is (d), Himachal Pradesh.
According to the 2011 census, the population of Christians in India was 27.8 million, or 2.3% of the total population. The states with the lowest Christian populations were Himachal Pradesh (0.2%), followed by Jammu and Kashmir (0.3%), and Uttarakhand (0.4%).
The low Christian population in Himachal Pradesh can be attributed to a number of factors, including the state’s history, culture, and demographics. Himachal Pradesh is a Hindu-majority state, and Christianity has not had a significant presence in the region for centuries. The state’s culture is also relatively conservative, and there is a strong emphasis on traditional values. This may make it difficult for Christians to integrate into the local community.
In addition, Himachal Pradesh has a relatively small population, which means that even a small number of Christians can make up a significant proportion of the total population. This may make it difficult for Christians to find a sense of community and belonging in the state.
Despite the challenges, there is a small but growing Christian community in Himachal Pradesh. The state is home to a number of churches and Christian organizations, and there is a growing interest in Christianity among the local population.
