Chashme Shahi is one of the biggest of three Mughal Gardens of Srinagar
None of the above

The correct answer is B. Raghunath Temple is built by Maharaja Ranjit Singh.

Panchraktan Mahadev Temple is the oldest Shiv Temple in Jammu city. It is located in the heart of the city, on the banks of the Tawi River. The temple is dedicated to Lord Shiva and is one of the most popular pilgrimage destinations in Jammu and Kashmir.

Chashme Shahi is one of the biggest of three Mughal Gardens of Srinagar. It is located on the banks of the Dal Lake and is a popular tourist destination. The garden was built by Mughal Emperor Jahangir in the 17th century.

Raghunath Temple is a Hindu temple located in Jammu city. It is dedicated to Lord Rama and is one of the most important temples in Jammu and Kashmir. The temple was built by Maharaja Ranjit Singh in the 19th century.

However, there is no historical evidence to support the claim that Raghunath Temple was built by Maharaja Ranjit Singh. In fact, the temple is believed to have been built much earlier, in the 16th century. The temple was renovated by Maharaja Ranjit Singh in the 19th century, but it is not clear whether he was the original builder of the temple.
