The minimized form of the logical expression $(\bar{A} \bar{B} \bar{C}+\bar{A} B \bar{C}+\bar{A} B C+A B \bar{C})$ is

  1. $\overline{\mathrm{A}} \overline{\mathrm{C}}+\mathrm{B} \overline{\mathrm{C}}+\overline{\mathrm{A}} \mathrm{B}$
  2. $\mathrm{A} \overline{\mathrm{C}}+\overline{\mathrm{B}} \mathrm{C}+\overline{\mathrm{A}} \mathrm{B}$
  3. $\overline{\mathrm{A}} \mathrm{C}+\overline{\mathrm{B}} \mathrm{C}+\overline{\mathrm{A}} \mathrm{B}$
  4. $\mathrm{A} \overline{\mathrm{C}}+\overline{\mathrm{B}} \mathrm{C}+A \overline{\mathrm{B}}$
