Task: Question Answering
Input (English): Question: In the homogeneous nucleation: 
 Options:  <1> If the solid particles formed under solidification have a radius less than the critical radius, the energy of the system will be lower if its size increases. <2> If the solid particles formed under solidification have a radius smaller than the critical radius, the energy of the system will be lower if it is redissolved. <3> If the solid particles formed under solidification have a radius greater than the critical radius, the energy of the system will be lower if it is redissolved. <4> If the solid particles formed under solidification have a radius equal to the critical, the energy of the system will be lower if it is redissolved. <5> There is no relationship between the critical radius and the tendency to grow in size or redissolve.
