In the following four periods:
$(i)$ Time of revolution of a satellite just above the earth's surface $({T_{st}})$
$(ii)$ Period of oscillation of mass inside the tunnel bored along the diameter of the earth $({T_{ma}})$
$(iii)$ Period of simple pendulum having a length equal to the earth's radius in a uniform field of $9.8 \; N/kg \; ({T_{sp}})$
$(iv)$ Period of an infinite length simple pendulum in the earth's real gravitational field $({T_{is}})$

• A
  ${T_{st}} > {T_{ma}}$
• B
  ${T_{ma}} > {T_{st}}$
• C
  ${T_{sp}} < {T_{is}}$
• D
  ${T_{st}} = {T_{ma}} = {T_{sp}} = {T_{is}}$
