how to create child records on the basis of parent record field multiselect picklist,if picklist have 1 value,create single child record.if picklist have 2 values,create 2 records of child

Here is an example with Account and Contact.

Let's say Account has MultiSelectPicklist__c which holds the values like this:

A1;A2;A3;A4

Then it will first create a List splitting the by ';' and then looping through the lstValues create a list on Contacts and then insert the Contact List.

Account acct = [Select Id, MultiSelectPicklist__c FROM Account WHERE Id = '<record Id>'];

String str = acct.MultiSelectPicklist__c;
List<Contact> lstCon = new List<Contact>();

if(str !=null)
{
    List<String> lstValues = str.split(';');
    for(String pkValue: lstValues)
    {
        Contact con = new Contact(AccountId = acct.Id, LastName='LastName ' + pkValue);
        lstCon.add(con);    
    }
    insert lstCon;
}
