I would like to ask this question from Clay Products in chapter Glass, Lime, Clay Products & Bricks of Construction & Building Materials

Answer 1

Right answer is (a) Low voltage porcelain is obtained by wet process

The best I can explain: Porcelain is prepared from felspar, clay, quartz and minerals and is non-porous, hard and brittle. Low voltage porcelain is obtained by the dry process while high voltage porcelain is obtained by the wet process.
