Answer:
Multiple sclerosis (MS) is the most common demyelinating and an autoimmune disease of the central nervous system characterized by immune-mediated myelin and axonal damage, and chronic axonal loss attributable to the absence of myelin sheaths. T cell subsets (Th1, Th2, Th17, CD8+, NKT, CD4+CD25+ T regulatory cells) and B cells are involved in this disorder, thus new MS therapies seek damage prevention by resetting multiple components of the immune system. The currently approved therapies are immunoregulatory and reduce the number and rate of lesion formation but are only partially effective. This review summarizes current understanding of the processes at issue: myelination, demyelination and remyelination—with emphasis upon myelin composition/architecture and oligodendrocyte maturation and differentiation. The translational options target oligodendrocyte protection and myelin repair in animal models and assess their relevance in human. Remyelination may be enhanced by signals that promote myelin formation and repair. The crucial question of why remyelination fails is approached is several ways by examining the role in remyelination of available MS medications and avenues being actively pursued to promote remyelination including: (i) cytokine-based immune-intervention (targeting calpain inhibition), (ii) antigen-based immunomodulation (targeting glycolipid-reactive iNKT cells and sphingoid mediated inflammation) and (iii) recombinant monoclonal antibodies-induced remyelination.Keywords: calpain, central nervous system, demyelination, fingolimod, glycolipids, lipids, multiple sclerosis, myelin, myelination, NKT cells, oligodendrocytes, remyelination, T cells

The correct answer is A (Automobiles).
Particulate matter is a complex mixture of extremely small particles and liquid droplets.
One of the major components of particulate matter is sulphate usually coming from sulphur dioxide found in exhaust fumes that have been produced by automobiles . Other components are nitrates , ammonia, sodium chloride and black carbon.
Other components of particulate matter come from dust, soot, smoke, industrial emissions.
Particulate matter is one of the most common contributor to air pollution.
