From laboratory investigations, the liquid limit, plastic limit, natural moisture content and flow index of a soil specimen are obtained as $60\%, 27\%, 32\%$ and $27$, respectively. The corresponding toughness index and liquidity index of the soil specimen, respectively, are

1. $0.15$ and $1.22$
2. $0.19$ and $6.60$
3. $1.22$ and $0.15$
4. $6.60$ and $0.19$
