If we have a valid non$-$empty list, lst$,$ but we wish only to iterate over the odd$-$indexed elements, which of the following is the best approach?

Question $19$ options:

Iterate through the entire list, keep a counter, and check to see if the counter is even or odd, and then perform the desired operation with the odd$-$indexed elements.

Use for i in range$(1,$ len$($lst$),2)$ to step through the odd indexed elements, and then use lst$[$i$]$ within the body of the loop.

Use a while loop with a counter.

Use for e in lst if i $\%2==1.$

None of the above.
