option:  \: (1) \: 2.103^{c}

Step-by-step explanation:

we \:  \: know \:  \:  \boxed{180° = \pi^{c}  \:  \: and \:  \:1° =  60'} \\ Now, \:  \:  \: 120° 30'  = 120° +  (\frac{30}{60} )° \\ \:  \:  \:     \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  = 120° +  \frac{1°}{2}  = 120.5° \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:    = 120.5° \times  \frac{\pi^{c} }{180°}  \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:    = 120.5° \times  \frac{3.14^{c} }{180°}  \\  = 2.103^{c}
