C. In 1997 a coalition government formed with the support of left and BJP (Incorrect)
D. In 1989, a coalition government was formed with the support of BJP and left front (Correct)
Explanation:
In 1991 the government that was formed under P.V. Narasimha Rao was supported by Congress and not BJP.
In 1997 coalition government was formed by the United Front with the support of Congress and not BJP.
The nineties also saw the emergence of powerful parties and movements that represented the Dalit and backward castes (Other Backward Classes or OBCs). Many of these parties represented powerful regional assertion as well. These parties played an important role in the United Front government that came to power in 1996. The United Front was similar to the National Front of 1989 for it included Janata Dal and several regional parties. This time the BJP did not support the government. The United Front government was supported by the Congress. This shows how unstable the political equations were. In 1989, both the Left and the BJP supported the National Front Government because they wanted to keep the Congress out of power. In 1996, the Left continued to support the non-Congress government but this time the Congress, supported it, as both the Congress and the Left wanted to keep the BJP out of power. |
