   Consider the given data with frequency distribution $$\begin{array}{ccccccc}{x}_i& 3& 8& 11& 10& 5& 4\\ f_i& 5& 2& 3& 2& 4& 4\end{array}$$ Match each entry in List-I to the correct entries in List-II. $$\begin{array}{ll}\text{List-I}& \text{List-II}\\ \text{(P) The mean of the above data is}& \text{(1) }2.5\\ \text{(Q) The median of the above data is}& \text{(2) }5\\ \text{(R) The mean deviation about the mean of the above data is}& \text{(3) }6\\ \text{(S) The mean deviation about the median of the above data is}& \text{(4) }2.7\\ & \text{(5) }2.4\end{array}$$ The correct option is:

   1. A.$(P)\to (3)(Q)\to (2)(R)\to (4)(S)\to (5)$
   2. B.$(P)\to (3)(Q)\to (2)(R)\to (1)(S)\to (5)$
   3. C.$(P)\to (2)(Q)\to (3)(R)\to (4)(S)\to (1)$
