<h2>Plasma is most likely inflence by - Option C</h2>

This plasma is most likely influenced by magnetic and electric fields. The massive positively charged ions which are influenced the lighter electrons than replace the ions to keep charge impartiality.

Therefore electric field influence the plasma. The movement of charged particles identical to a magnetic field line is not influenced. Plasma contains charged particles which are positive nuclei and negative electrons which can be molded and restricted by magnetic forces.

Alike iron filings in the closeness of a magnet, bits in the plasma will ensue magnetic field lines.

#1

Ag is found as too less reactive so

Cu✓
Al✓
Ca✓

#2

No element in universe can displace potassium (K) from its solution as it's most reactive .

Nota

#3

Fe is also a reactive metal.

Only Cupper is less reactive than it

So

Al✓
Ca✓

#4

Only Calcium can displace Mg

#5

Mg and Ni can do ,Aurum(Gold) is least reactive so can't

#6

Only Mg

#7

Only Mg

#8

Mg and Ni

#9

Only Zn

#10

Zn and Pt

#11

Nota

As Ca is third most reactive metal

#12
