The given figure shows the mechanism of action of FSH on its target cells.
I: FSH is hydrophilic and hence cannot enter the cell and therefore acts via a second messenger.
II: The second messenger will cause physiological responses after binding to a receptor present in the nucleus of the cells and then influencing the level of gene expression in the target cell.

1. Only I is correct
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect
