ΔS is negative when the number of moles of products is less than the number of moles of reactants. In option A, a solid (Sr(OH)2) is formed from aqueous ions and LiNO3. The number of moles of products (Sr(OH)2 and LiNO3) is less than the number of moles of reactants (Sr(NO3)2 and 2LiOH). This means that the reaction has a decrease in entropy, and ΔS is negative.
