Explanation:

On March 4, India entered the second stage of its nuclear power programme by starting the core-loading process of the prototype fast breeder reactor (PFBR) at the Madras Atomic Power Station, Kalpakkam. India's ambitious nuclear program is a three-stage endeavor designed to achieve long-term energy security. The first stage centers around Pressurized Heavy Water Reactors (PHWRs). These reactors were chosen for their ability to efficiently utilize natural uranium, a readily available fuel source in India. This efficiency stands in contrast to Light Water Reactors (LWRs) which require enriched uranium, necessitating complex enrichment facilities.  Furthermore, India opted to develop its own heavy water production capabilities instead of relying on uranium enrichment.

Here, statements I and II both are correct and statement II is the correct explanation of statement I. Hence, option (a) is correct.
