Can you please answer this essay question for me.

"Four positions on constitutionalism have been described: first, a conservative position, which insists that the South African Constitution (Constitution) should protect existing rights and affirm the status quo , and believes that transformation is an ideology; secondly, a constitutional optimism that subscribes to the transforming success of the Constitution; thirdly, a critical position that since the early 1990s cautioned against an over-optimistic or over-romanticised vision of the Constitution, but that has nevertheless not rejected the ideal of constitutionalism and has continued to push for radical change by re-interpreting the law, the Constitution and jurisprudence; and fourthly, the position that argues for the Constitution to be abolished, for a delinking, holding that the Constitution not only furthers past legacies, but as such manifests much if not all of the fraught past." (Karin van Marle "Hold onto Critical Jurisprudence" (2019) 23 Law, Democracy and Development 203) The above quotation is from an article by South African legal theorist Karin van Marle (now based at UFS) where she argues for a "critical jurisprudence that responds to the many complexities that South African society faces... " (p. 204). Reflect on the quote above and write an essay in which you discuss the main themes of critical theories of law / critical jurisprudence and their possible contribution to transforming South African law. Draw on these critical themes to engage with the post-1994 constitution, constitutionalism and the constitutional order in light of the four positions explained above. Develop an argument on which among those four approaches (legal conservatism; constitutional optimism; critical skepticism and constitutional abolition) is more or most suitable for responding to South Africa's past and present of oppression, injustice, inequality and disharmony. Your essay should include: . A discussion of the main / common themes of the critical theories of law (emphasis can be placed on a specific critical theory of law that best reflects these themes); . Application of the theoretical discussion above to present debates about the successes and/or failures of the constitution and about whether the constitution is an instrument of transformative social change or whether it hinders more radical change (with reference especially to the different views of Klare and Madlingozi). The essay should focus on jurisprudenceal and theoretical analysis
