Arrange the following multiples in decreasing order:
(I) Milli
(II) Centi
(III) Nano
(IV) Pico
A. IV, II, I, III
B. II, I, III, IV
C. I, III, II, IV
D, III, IV, I, II

Explanation

Solution

When the magnitudes of physical quantities are large or small, preference in power of 1010 are used which are given here.

Complete step by step answer:
When the magnitudes are very large as very small, it is convenient to express them in the multiples of the SI units
(I). Milli
It is used to express 10−3{10^{ - 3}}
(II). Centi – It is used to express 10−2{10^{ - 2}}
(III). Nano – It is used to express 10−9{10^{ - 9}}
(IV) Pico – It is used to express 10−12{10^{ - 12}}
As, 10−2>10−3>10−9>10−12{10^{ - 2}} > {10^{ - 3}} > {10^{ - 9}} > {10^{ - 12}}
So, centi >>Milli >> Nano >>Pico
So, the correct decreasing order of multiples will be
(II), (I), (III), (IV)

So, the correct answer is “Option B”.

Additional Information:
The list of various prefixes of powers of 1010 are,

S.NOMultiplePrefixSymbol
1.101{10^1}DecaDa
2.102{10^2}HectorH
3.103{10^3}KiloK
4.106{10^6}MegaM
5.109{10^9}GigaG
6.1012{10^{12}}TeraT
7.1015{10^{15}}PetaP
8.1018{10^{18}}ExaE
9.10−1{10^{ - 1}}DeciD
10.10−2{10^{ - 2}}CentiC
11.10−3{10^{ - 3}}MilliM
12.10−6{10^{ - 6}}Microμ\mu
13.10−9{10^{ - 9}}NanoN
14.10−12{10^{ - 12}}PicoP
15.10−15{10^{ - 15}}FemtoF
16.10−18{10^{ - 18}}AttoA

Note:
Remember that in negative power, as the negative power increases, the value decreases.
So, the correct order there is
(II), (I), (III), (IV)
Not (IV), (III), (I), (II).
