Assertion: In the 1996 elections the BJP government could not secure a majority in the Lok Sabha.
Reason: Most of the other parties were opposed to its policies.

Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion.

The BJP continued to consolidate its position in the elections of 1991 and 1996. It emerged as the largest party in the 1996 election and was invited to form the government. But most other parties were opposed to its policies and therefore, the BJP government could not secure a majority in the Lok Sabha.
