$3.$ Should Tata Motors consider a scrip dividend instead of a cash dividend, to conserve liquidity? How would a scrip dividend affect capital structure?

$$ Evaluating the impact of a scrip dividend on Tata Motors' capital structure would involve calculating the dilution effect, changes in debt$-$to$-$equity ratio, and comparing liquidity effects of cash vs$.$ scrip dividends.

Can someone help me to identify the formulas to use in the "involve calculating" process $($dilution effect, changes in debt$-$to$-$equity ratio, and comparing liquidity of cash vs$,$ scrip dividends$)$
