Option(A) is correct.
mass of C=3.758g
mass of H=0.316g
mass of O=1.251g
moles of C=3.758/12=0.3132
moles of H=0.316/1=0.316
moles of O=1.251/16=0.0782
  mole %:
             'C'=44.274%=44%
             'H'=44.67%=44%
             'O'=11.054%=11%
              empirical formula of compound=C_4H_4O
