Answer
1: in electronics; 2 : free electrons
Explanation
This is a fill in the blank type question and we need to find suitable words or phrases fitting the blanks in this sentence "GRAPHENE has the potential to be used __(1)__ because its bonding allows for __(2)__ that can carry charge." Graphene is a single layer of carbon atoms and has excellent electrical conductivity and strength due to its bonding acquisitions. Options include using it:1: In electronics or, as a catalyst, and2: Its bonding allows for free ions or free electrons.Let's look at each fill-in blank options in the given answers:'In electronics' seems suitable for first blank as this usage of Graphene aligns with its material proprieties.For the second blank, since the electronic properties are due to the movement or transmission of electrons, 'free electrons' seem to be a suitable phrase.So let us compare the options which combine both of these phrases and have the potential to provide a suitable and sensible possibility.Thus from all the given options, option "1: in electronics; 2 : free electrons" aligns with both the conditions that we deducted above.
