Would conditions of +ΔH and -ΔS favor a spontaneous or non-spontaneous reaction? Why?

If the enthalpy change is positive +ΔH and the entropy change is negative -ΔS, the free energy change is always positive and the reaction is never spontaneous, therefore, letter A

An increase in Entropy means that the system is more in disorder, some examples of daily situations where we have an increase of entropy: Ice melting (the ice crystals are becoming less organized with the melting); Salt or sugar being dissolved in water (the crystals are being dissolved, releasing ions and making a solution); boiling water (the water molecules becoming more agitated and becoming gas). These cases are what we have in Letter A (a solid being dissolved into ions in a solution); Letter C (solid CO2 having heat added and becoming gas); Letter E (C12H22O11 in solid form being dissolved)
