Answer the following by appropriately matching the lists based on the information given in the paragraph.
A musical instrument is made using four different metal strings, and with mass per unit length and respectively. The instrument is played by vibrating the strings by varying the free length in between the range and It is found that in string- \left(\mu\right){L}_{0}{T}_{0}{f}_{0} .( a )- 1\left(\mu\right)( p )1( b )- 2\left(2\mu\right)( q )\dfrac{1}{2}( c )- 3\left(3\mu\right)( r )\dfrac{1}{\sqrt{2}}( d )- 4\left(4\mu\right)( s )\dfrac{1}{\sqrt{3}}( t )\dfrac{3}{16}( u )\dfrac{1}{16}1, 2, 34{L}_{0}, \dfrac{3{L}_{0}}{2}, \dfrac{5{L}_{0}}{4}\dfrac{7{L}_{0}}{4},1, 2, 34{1}^{st}, {3}^{rd}, {5}^{th} and harmonics, respectively such that all the strings have same frequency. The correct match for the tension in the four strings in the units of will be.
