Hi yagyadeepk,
You can achive this through the process model by following these steps.
1.index the column that you want to update and use update array to update the column at particular index( for your scenario updateArray(index(CDT,"C"),2,"new value")).
2. save this to the column c of your cdt in the script task. as shown in the snapshot. This would help you.

You can also configure the data output to write to that field, and instead of 'is saved as' choose 'is stored at index ...' for your operation.

You can try updatearray() to update the C column, using wherecontains() to get you the appropriate index

Hi yagyadeep, we have multiple ways to do this, you can update/modify the DB data using write to data store entity smart service node.
For example:
In Script Task Data Inputs,retrieve data from DB by primary key of that 3rd row and store it in respective CDT Type acp parameter (say cdt_sample).
Data outputs,
1. Store that acp Parameter in pv value
2. the modified value placed in Custom output expression and stored as cdt_sample.c
Go through this link forum.appian.com/.../Write_to_Data_Store_Entity_Smart_Service.html
you can get better idea.
It may help to you
