a. 1
b. 2
c. 3
d. 4

There are 3 terms in the given expression.       Option(c)

Step-by-step explanation:

Given expression is:

3x²y⁴z - 6xy - 3z(5x²)

Here number or variable multiplied with variable before the operator (like +, - etc) that is called the one term in the expression.

From given expression:

First term is :  3x²y⁴z

Second term is : 6xy

Third term is : 3z(5x²) = 15zx²

So, there are total three terms in the given expression.

That's the final answer.
