A single crystal intrinsic semiconductor is at a temperature of $300$ $\text{K}$ with effective density of states for holes twice that of electrons. The thermal voltage is $26$ mV. The intrinsic Fermi level is shifted from mid-bandgap energy level by
1. $18.02 \: meV$
2. $9.01 \: meV$
3. $13.45 \: meV$
4. $26.90 \: meV$
