Select select = new Select(driver.findElement(By.cssSelector("*[name='testproject']")));
select.selectByVisibleText("C");
How to identify/select a option from the drop down. Please help me with this.

Answer 1

Since this is a cssselector, use By.cssSelector instead of By.name
Select select = new Select(driver.findElement(By.cssSelector("[name='testproject']")));
If you want to use By.name, then use like this:
Select select = new Select(driver.findElement(By.name("testproject")));
NOTE:- In both the cases above, I am assuming there is one element "select" with the class "testproject". But, if that's not the case then you have to use the first code for cssselector and change the code to ;
Select select = new Select(driver.findElement(By.cssSelector("select[name='testproject']")));
