Answer 1

I think you were really close with your solution. This code worked for me. I put comments inline to explain the couple changes I made.
$ie = New-Object -ComObject InternetExplorer.Application
$ie.visible=$true
$ie.navigate2('https://www.nseindia.com/companies-listing/corporate-filings-insider-trading')
while($ie.Busy) {Start-Sleep 1}
$dropdown = $ie.Document.body.getElementsByClassName('dayslisting') # You needed to select .body here to use getElementsByClassName
$3m = ($dropdown[0].all | where {$_.innerHTML -like "3M"}) # Dropdown is a list because classes can be assigned to more than one element. I'm getting all elements of the first list, but you could do something better if you wanted.
$3m.click() # Click the "3M" button.

The below code can also help to click on the 3M option on the list.
$ie = New-Object -ComObject InternetExplorer.Application
$ie.visible=$true
$ie.navigate2('https://www.nseindia.com/companies-listing/corporate-filings-insider-trading')
while($ie.Busy) {Start-Sleep 1}
$dropdown = $ie.Document.getElementsByClassName('dayslisting')
$link = $ie.Document.links | Where-Object {$_.outerText -eq '3M'}
$link.click()
