Try this:

select ProjectName,  
ProjectNos,  
isnull([Questionnaire Submission for sripting],'') as c1,  
isnull([Programing of questionnaire and/or ConJoint Design/Email Send out],'') as c2,  
isnull([Quality Check (Desktop and Mobile)],'') as c3,  
isnull([Questionaire link sent to client for review],'') as c4,
isnull([Hard Launch],'') as c5,  
isnull([Data Collection],'') as c6,  
isnull([Quality Check (Sampling)],'') as c7,  
isnull([Status of sampling process sent to client],'') as c8,  
isnull([Data Exported & Cleansed],'') as c9,  
isnull([Coding of Open Answers],'') as c10,  
isnull([Table Report],'') as c11,  
isnull([PPT Report],'') as c12,  
isnull([Data Analysis],'') as c13,  
isnull([Raw Data Delivery to CDT],'')as c14,  
isnull([Quality Check ( Table Report/Raw Data)],'')as c15,  
isnull([Power Point Quality Check ],'')as c16,  
isnull([Final Presentation Delivery to CDT],'')as c17,  
isnull([Extra Analysis (after presentation)],'')as c18,  
isnull([N-visualize report],'')as c19,  
isnull([Excel Delivery],'') as c20 
from (
    select ProjectName,  
    ProjectNos,
    Status_Name,
    [Task_assigned] 
    from tbl_ProjectDetails
    where flag='0') as t
PIVOT   ( 
 max(Status_Name) for   
 [Task_assigned] IN   
 ([Questionnaire Submission for sripting],  
 [Programing of questionnaire and/or ConJoint Design/Email Send out],  
 [Quality Check (Desktop and Mobile)],  
 [Questionaire link sent to client for review],  
  [Hard Launch],  
 [Data Collection],  
 [Quality Check (Sampling)],  
 [Status of sampling process sent to client],  
 [Data Exported & Cleansed ],
