Answer 2

Hi.

The most metallic elements among Li,  K, Na and Fr is Potassium (K).

@@@-----Reason-----@@@
As we move from top to bottom in a group the metallic character increases due to the increases in number of shells. The elements given above are the members of Group 1 in the Periodic Table. In this group, hydrogen lies at the top, then lithium, sodium, potassium,rubidium,cesium,francium.  France is not most metallic because it is radioactive and cesium is not given in the above metals thus potassium is the correct answer.
