Molar mass of BaSO4 = 233 g

\mathrm{\therefore moles\: of\: BaSO_{4}= \frac{1. 44}{233} = moles\ of\ S}

\mathrm{\therefore mass\: of\: S\, present= \frac{1. 44}{233}\times 32} 

\mathrm{\therefore % \,S = \frac{1. 44\times 32 }{233\times 0. 471}\times 100 = 41.98%}

Hence, the correct answer is 42
