Q.11 Let P and Q subset of R. Define P+Q=(x+y|xp. ye Q} pick the true statements If A and B are closed sets, then A+B is closed set If A and B are closed set, then A+B is compact set If A is open set and B is a closed set, then A+B is open set If A is open set and is closed set, then A+B is closed set.
