The answer is A.

Rubies are commonly used in creating lasers; this gem was used in the first lasers, although nowadays synthetic rubies are used more often due to their low cost in comparison to the real gem.

intuitionist

An intuitionist type of morality entails that model of moral reasoning that makes a judgment off intuition, then later tries to reflect if the judgment was reasoned through in the correct manner.

Here an individual just goes ahead to make a judgement from his intuition, but will later go back to analyse if the was rightly passed or not.

The people act intuitively during laboratory games, hence, desire to punish wrongdoings is driven mostly by automatic emotional reactions rather than by deliberate conscious calculations.
